1. Intro: Hey, and welcome to my course on understanding diminished harmony. Now, this is a course that I've been writing for about three years now. I already have about 25 courses on the Internet, and the whole time I was ready to jump in with this diminished harmony course, but I wanted to make sure that it was really ironclad and made a lot of sense because diminished harmony can be, quite honestly, quite confusing sometimes. Now, whether you're hoping to learn more about diminished scales, the function of diminished harmony, what a diminished seventh even is at the most basic level, I really want to make sure that I take diminished harmony and blow away all the fog so that you can start to use it in your own original compositions or at least better understand what other composers and songwriters were thinking when they applied diminished harmony. Now, I've always said, I harmony is the body of music, diminished harmony is the veins and the nerves. It runs through everything else, and as a result, it's a little bit more abstract at times. It's a tense sound. It can take us to many different places. But my hope is that this course can help you have a framework for understanding diminished harmony so it doesn't feel so confusing. Now, personally, I use diminished harmony quite often as part of my modulation. There's a lot of different chord shapes that when you change them slightly, you get a diminished chord, which can then take you to a whole new area within your song harmonically. So that's one thing that I'm going to be focusing on towards the end of this course. But again, we're going to start with the basics, and we're really going to try to work our way up so that you can pause as needed, digest the material apply the material and then jump back in when you're feeling ready. Now, the class project within this course is going to be you taking either a song that you're working on or a chord progression that you already know. And you're going to try to take one to two of these diminished tricks that I've taught you within this course and apply it within that song or progression. From there, you're going to submit the project so that I can review it and give you some feedback. Whatever diminished tricks you choose should give you some sort of idea how you enjoy diminished harmony. Is it as part of a modulation? Is it as part of prolonged tension? It really depends on what tricks you pick, but that's going to give you a clear idea of what you appreciate the most within diminished harmony. And as always, there's going to be a full class outlining all the details for this class project. So make sure that you check it out before submitting. Now, by the time you're done this course, you should feel more confident using diminished chords as a composer. Understanding how they're being used within some songs that you're learning and just generally having access to this more menacing sound of diminished chords in their various forms. I look forward to jumping into this with you. We're going to start off nice and basic, and we're going to take things one notch higher at a time so that you can understand the basics of diminished harmony or really understand how to use them at a more professional level. So up ahead are all of my favorite uses of diminished chords. So let's start to break things down one step at a time. I'll catch you in the first class. 2. Class Project: This class project, you're either going to take a song that you're writing or a song that someone else has written that you're working on, and you're going to try to implement one to two of these diminished tricks within that composition. Now, you're going to have to try various tricks in various spots within the progression before it feels natural and before it works. But when it does click and when it does feel like it's working, that's something really important to note. Is it that a certain type of diminished chord is leading you in a certain direction? Is it that you've changed a certain chord into a diminished chord and you really like that sound? This is ultimately going to show you what you like about diminished harmony and how you might want to apply it within the future. So don't just plunk diminished chords into a progression and then submit it. Make sure that you're doing some trial and error and seeing what you like the most in terms of the results. From there, you're either going to do an audio or video recording that you will submit to me through a link within the course description. Can use YouTube or Vmeo if you're doing a video submission, or you can use something like SoundCloud if you're doing an audio submission. But one way or another, supply me with a public link so that I can easily check it out and give you some feedback. Now, within this submission, I want you to make sure that you're recording the original progression, as well as this altered progression using the diminished tricks. So once I've heard the original progression and then this new progression using the diminished tricks, I'll let you know how I think it has improved, as well as some other directions that you could have taken these harmonic alterations. Make sure that you're recording things on a day that you're feeling in the zone and really ready to record. Do some prep work beforehand so you're not just rushing through this project. I want to see the results of you really working through what you think works best so that I can give you my most honest feedback. So don't stress about it. Have some fun with it. I hope you enjoy doing this class project, and I'll catch you in the next class. 3. What is a Diminished Chord: And Alright, let's dive into talking about diminished harmony. First, we're just going to talk about what is a diminished chord. A diminished chord is sort of like a minor chord with a flattened top note. So if we take something like C minor and take the top note and lower it to semitone, we have C diminished. To diminish something means to make it smaller. And that's, after all, why we're calling these chords diminished chords. So we've taken a minor chord and we've flattened the top note. Now, I want to be clear, a chord like C sharp minor. When we flatten the top note, all I'm talking about is lowering it a semitone. I'm not trying to say that it always has to go to a flat black note. First learned this is a D flat, this is an E G flat A flat B flat. But if you have something like A G sharp, and you lower it to a G, that is also flattening the note. So the top note goes down a semitone might be a more universal way of saying it, but ultimately, we are flattening that top note. Now, another way of thinking about diminished chords is to move up a minor third two times. So I have a C three semitones is a minor third. Three semitones is a minor third. Now I have C diminished. Another way of thinking of diminished being small relating to these chords is that minor chords use a minor third and then a major third. So in other words, three semitones, four semitones. A major chord goes up a major third than a minor third. In other words, four semitones than three semitones. But the diminished chord only uses the smaller of those two intervals. So minor third, minor third, it's using the smaller interval every time it is smaller, it is diminished. These diminished chords sound innately very spooky. Just give it a listen. I kind of sounds like the chord they would use in, like, Halloween music or something tense in a horror movie. They're meant to represent tension and they want to resolve. You can probably even tell where they want to resolve. Listen, if I go through all the chords in a C major scale and I stop on the seventh where our diminished chord is located, you can hear this attraction pulling up. So for now, I want you to think of diminished chords as pulling up one semitone to resolve. They will more often resolve up to a minor chord, but they can resolve to majors as well. So just listen, we have B diminished to C major and B diminished to C minor. The diminished to minor is sort of like spooky to sad, whereas the diminished to major is sort of like spooky to happy if I really gloss over the emotional quality of these chords. That being said, spooky to happy is very juxtaposed. Technically, it works theoretically. It was used plenty in the romantic era and classical and even as late as Baroque, but it sort of caught a second wind in the romantic era and got used a lot in major music. Even something like Claire DeLun in the first few bars, experiments with major and diminished harmony. All that is to say, the diminished resolving to minor just kind of makes more sense in terms of what your harmony is telling as a story. Now, diminished chords, as we first start to learn about them, are situated on the seventh degree of a major scale or a harmonic minor scale. So where we're going to find this chord if we go through C major is on that seventh note. You can see we have B, up three semitones, up three semitones, or B minor with the top note flattened. There is our B diminished chord. And this is also true for harmonic minor scales. C harmonic minor, for example, is going to give us a lot of different types of chords, where we have this sort of sound working up through the different chords, and there it is, again, B diminished built on the seventh scale degree. Here's B, we're skipping, D, we're skipping E flat and F. Again, we're skipping no within our scale to create these chords. As a function, diminished chords are also used quite often as modulators to take us into other keys. So if I'm in C minor, I can use a particular diminished chord to take me into something like F minor or G major or some other key to help extend a song so that you're not stuck in one key for too long. We will be discussing modulations much later. I think it's class eight, but for now, I just wanted to mention that there's going to be plenty of use for these diminished chords as modulators. So that is how a diminished chord sounds, basically how they function, where you're going to find them and how they're constructed. In the next class, we're going to expand them into diminished seventh chords, where they sound a little bit more tense and the harmony gets a little bit more complex. So let's talk about diminished seventh chords. I'll see you there. 4. Diminished 7th Chords: All right, let's talk about diminished seventh chords. To start, they aren't that much more complex in terms of how to create the shapes, but their function can be quite intricate within different progressions. So back to our example of C major, if I was to start on the seventh note, which is a B, skip a note to D, skip a note to F, and skip a note. A, I don't quite get a diminished seventh chord. So diminished seventh chords are simply diminished chords with an additional minor third. So we're thinking a note to up three semitones, up three semitones, up three semitones. In other words, up a minor third, up a minor third, up a minor third. And so with this extra note that we've added, this distance from bottom to top is actually called a diminished seventh. Sort of like a major seventh chord, the outside notes span a major seventh. Or a minor seventh chord, the outside notes span a minor seventh. In this diminished seventh chord, the outside notes span a diminished seventh. But what is a diminished seventh? So if I go from B to B, this is an octave, a letter up one pattern higher to the same letter. Down a semitone is a major seventh. Down a tone from that top note is a minor seventh. And if I go down one more semitone, I've stretched that seventh as low as it can go. This is a diminished seventh. Now, it also looks a lot like a major six, the sixth note from a major scale, but it depends on how you name it. So, for example, this C to this G sharp, that is a major six. But what if I was to call this note an A flat instead of a G sharp? BCDFGAG from B to A is a seventh, a sharp was our major seventh, a natural was our minor seventh, and a flat is our diminished seventh. What's really interesting is this is where you can start to get things like double flats. For example, C to C is an octave, C to B is a major seventh. C to B flat is a minor seven C to B double flat is a diminished seventh. So you always want to first consider what is the letter that I'm using for that seventh? And then what accidental, sharp, flat, double flat, in this case? Which accidental do I need to use to properly name it a diminished seventh? Now, to be honest, the sharp doesn't find its way in there, nor does it natural, but flats and double flats are going to be very common. Now, back to C major as our main key. If I go through all of the chords in C major, as we talked about, the seventh chord is going to be the diminished chord. But if I go to make it a diminished seventh, I'm pulling in a black note, A flat, which does not come from C major. So where exactly are we extracting this chord from? I first want to make it clear that you could play a B diminished seventh and resolve to C major. Plenty of people have done it. It's not staying absolutely true to the key of C major, and technically, there's something called the C harmonic major scale. I bet you probably haven't heard of it, and I bet you probably won't need to use it, but it sort of justifies how we can pull out this B diminished seventh chord within a major scale environment. That being said, where we're going to naturally find this chord is in the harmonic minor scale. So in C harmonic minor, our notes are C, D, E flat, F, G A flat, B, C. Starting from that B, the seventh note, I skip C to D. I skip E flat to F, I skip G to A flat, and there's our B diminished seventh chord. In this case, B diminished seventh wants to resolve to C minor. And listen to that sound. It's so gorgeous. Very spooky, very classical sounding. It's just an iconic sound. Now, by adding this extra skip, we are creating a bit more tension. There's just this minor third, minor third, minor third. It's a very tense sort of sound. But what's cool about this is as we start to invert it, it inverts into other diminished chords. And we're going to dive really deep into this in the classes to follow, but I want to briefly mention what this is all about. So if I have B diminished seventh and I put it in first inversion, sure, we could call this B diminished seventh, first inversion. However, this is also all the notes that are needed. For D diminished seventh, D, up three semitones, up three semitones, up three semitones. Same with F, and same with the A flat. Basically, any of the four notes in this diminished seventh chord could be a diminished seventh chord. So B diminished seventh, D diminished seventh, F diminished seventh, and A flat diminished seventh. And even just moving through them is a very iconic sort of sound. Check this out. Right? Like from church organ music, we're going to hear this climbing sort of tension. Also in, like, Halloween music, we hear that a lot as well. But there's one thing I want to mention, which is that as we go through these inversions, we are kind of cheating a little bit. We talked about B going up a skip, going up a skip, going up a skip, and we get B diminished seventh. But D, if I go up a skip and then up a skip and then up a skip, I get a different chord. I get D minor seven flat five. F, if I go up a skip, up a skip, up a skip, I get F minus seven. And a flat, if I go up a skip, up a skip, up a skip, I get A flat major seven. So why is it that the B, when I move up skips, I get a diminished seventh chord, but D F or A, the second note, the fourth note, and the sixth note, I don't naturally get these diminished chords. Well, it's because B diminished seventh is sort of like the main diminished seventh chord of C minor. And with small alterations, we can make D F or A flat diminished chords, as well. So the big question is, what is the alteration? It is simply just not skipping one of the notes. D, up a skip, up a skip. And then just straight to that next note. This is in the harmonic minor scale, part of what makes the scale unique. If I go up from C, it's tone semitone, tone, tone, semitone, and then a tone and a half, a minor third. It's already in the scale, whereas it would not usually be within a scale this distance of three semitones or a minor third. So we're going to take advantage of that and choose to not skip once we hit this interval. We're just going to simply move from the A flat to the B and not skip over that B. So in this case, we have D, up a skip, up a skip, and then straight to the next note of that scale. F, up a skip straight to the next note, up a skip, A flat, straight to the next note, up a skip, up a skip. So you can see if when we hit this flat six to seven, so you can see that when we hit this flat six to major seven, that natural minor third that's happening, it's technically called an augmented second, but it's all kind of the same thing for what we're talking about. When you hit that area, you don't want to skip to an additional note because you already have that minor third, augmented second, three semitones, whatever we're calling it. So just something to keep in mind. When I first started to play around with diminished harmony, I kind of recognize that diminished seventh chord off the seventh scale degree happened very naturally. But I couldn't find out why when I inverted the chord, I got all these diminished chords, but it's not naturally skipping notes within the scale. There's a little bit of an adjustment based on the fact that this scale has that unique interval within it. So now that we've talked a little bit about how the second, fourth, and the sixth note of a harmonic minor scale can give us two different types of chords. It can give us a diminished chord if we make sure to not skip at certain points, and it can give us other chords like major seventh, minus sevenths or half diminished sevenths, aka minus seven flat five chords. We have some options for substitutions with diminished chords, and that's what we're going to talk about. In the next class. I'll see you there. 5. Diminished Substitutions: Let's get talking about Diminished Substitutions. We're going to start by talking in the minor environment where our diminished seventh chord originally comes from, and then we'll talk a little bit about how this also works in a major environment. So in the last class, I talked about how we very naturally get this B Diminished 7th Chords within our C harmonic minor scale. And as we go up through its inversions, we end up getting a total of four different diminished chords that are available. Now, naturally, this B, if I go up a skip up a skip up a skip is the only chord available starting on that seventh scale degree. But if I start on the second scale degree, in other words, that second diminished chord that's available, sure, on the second scale degree, the D diminished seventh, in this case, is available. But if I'm true to the key and I go up skip skip, skip, I end up getting something called a minor seven flat five. This is another chord that's available as opposed to the diminished seventh chord. If I go up to the fourth scale degree, we talked about how F, in this case, F diminished seventh is available. But also if I go up Skip Skip I get F minus seven. And lastly, on the sixth scale degree, the flat six to be specific, if I go up a skip, a skip, a skip, I get an A flat, major seven chord available. So let's say we extend a chord progression, something like C is our minor one, A flat, major seven, F minus seven. D minor seven flat five, and then we're going to play a G dominant seven before coming back to C minor. First of all, if that sounds confusing, I would say learn a little bit more about the basic seventh chords before you dive too far into diminished harmony. But I don't want you to feel like at this point in the course, you're like, Oh, my God, it's going to be so much of this type of harmony moving forward. It's really not. Think of it this way. On the first scale degree, we have C minor, pretty easy PZ. On the sixth scale degree, A flat, we're just going up skip skip skip. Don't worry about what it's called. It is called A flat major seven. If you don't know that, something to learn on the side. And then we did the same thing on the four chord and the two chord. Again, two, four, and six are important because when I take this diminished seventh cord in its natural habitat, starting on the seventh scale degree, as I invert it and pull out those other diminished cords, they're built off of scale degree two, four, and then this flat six, a flat, in this case. So I was just showing you as I'm going down through these cords, the natural cords that they want to be A flat major seven, F minor seven, D minor seven flat five, we're going to start with those as our starting point. And then to get back to one, I'm playing G major or G dominant seven. It's a really classic sort of move to take us back. To C minor. In fact, let's go even more simple. Let's use the B diminished seven to take us back to C minor. So we'd have C minor, down a skip, down a skip, down a skip, down a skip, and then resolving back to C. Now, what's cool about this is we can take any one of these chords that are not diminished, not the first chord, not C minor. So A flat, F or D, we can take any one of those three notes and substitute them for a diminished chord. So let's try this out. We have C minor. Instead of A flat major seven, let's play A flat Diminished seven to F minor. And then our D minus seven, flat five, B diminished seven back to C minor. Next, we're going to try it with instead of the A flat being substituted for Diminished Chord, we'll try it on the F minor. Did you hear it? So we had this A flat major seven F Diminished seven, D minor seven flat five, B diminished seven to C minor. Now we're going to try it instead of D minor seven flat five. We will try D diminished. And this sort of move, by the way, you hear a lot in Chopin's music. So a minor seven flat five turning fully diminished or vice versa. It sets up different harmonic movement and can kind of pivot around certain keys and modulate in a fun way. Let's try it out C minor, A flat major seven, F minus seven, all very natural chords from our key. Here's our Diminished Chord down to B diminished, and then back to C. You could also substitute every one of them. C minor, A flat, Diminished seven F, diminish seven, D, Dimini seven, B, diminish seven. C minor. So the point here is that if you're playing a chord progression in a minor key and you have the two, four or flat six chord as its sort of normal variation, like the A flat major seven, the F minor seven, or the D minor seven flat five, you can substitute any one of them or potentially all of them for Diminished 7th Chords. Now, this gets really unique when you pull it into a major environment. So first of all, if I'm in C major, as we know, this A flat doesn't really exist in the key, but we're still going to work with it. That being said, where you're going to find substitutions is more often going to be on the two and the four. The B already gives us a diminished sound, but in C major, we would have D minor or D minor seven if we add an extra skip, and then on the fourth scale degree, F major or F major seven if we add an extra skip. A flat isn't really available, so for now, we're going to gloss over that. But let's say I'm in C major. I'm going to play a basic progression, two, five, what? Very common in jazz. We could even add some extra skips, two, five, one. Now I can take the two and substitute it for a Diminished Chord. 12, five, one, and same with the four chord. So if we go one, four, five, one, let's try the four as a Diminished Chord. One, four, five, one. Again, if you want to hear this one to a diminished four within a piece, check out Claire DLune It is the initial progression from Debussy's Claire DLune. Tell me if you recognize this. Okay, so we have this D flat major, and then G flat, Diminished seventh with some side stepping, but there it is. And it's on the fourth scale degree. So substituting the four chord for a diminished seventh chord. It's almost like diminished harmony had been used so much in the minor environment during the classical era that romantic composers decided to sort of turn it on its head a little bit and pull it even more into major music. I'm not saying that diminished harmony was not used in major music in classical embarque music. Saying though, is that romantic music really opened up the floodgates and started using it a bit more. So those are some great diminished substitutions to get you started with pulling Diminished 7th Chords into chord progressions to make them sound more classical, more tense, and generally more diminished. In the next two classes, we're going to start to talk about octatonic scales, AKA, diminished scales. So in the next class, we're going to talk about the whole half-diminished scale. I'll see you there. 6. The Whole Half Diminished Scale: So we are going to talk about the whole half diminished scale, which is an octatonic scale. In other words, usually there's seven notes within a major or a minor scale. An octatonic scale, oct being eight is going to have eight individual notes before it reaches its octave. And we arrive at these notes by moving up a tone and then a semitone and then a tone and then a semitone or whole step, half step, whole step, half step, same idea. So that's the one we're going to talk about first, where we move up a whole step and then a half step and then repeat. Let's take a look at how it sounds. We have C, up a tone, up semitone, the tone up semitone, up a tone, up semitone, up a tone, up semitone. And we end up getting one, two, three, four, five, six, seven, eight different individual notes. Now, for those of you that know a melodic minor scale, sometimes called the jazz minor scale, if you play one of these scales, and then take the fifth and substitute it as a flat version and a sharp version, so we really don't have the stability of that fifth. You're going to play the scale with these two versions of the fifth. So C, D, E flat, F, and then instead of G, we get G flat G. A, B, C. It's kind of like a melodic minor scale with this sort of double altered fifth. But ultimately, tone, semi tone, all the way up, that's going to get you there. Now, if we start to extract the basic harmony from this, we're going to get a whole lot of diminished chords. Check this out. So C up a skip in the scale, up a skip in the scale, up a skip in the scale, gives us C diminished seventh. Of course, if I go up an extra skip, I'm just back to C. So we're going to ignore any extra skips from there. So we have C diminished seven. Let's start on D. Up a skip up a skip up a skip D diminished seven, E, up a skip up a skip up a skip, E flat, diminished seven. And every single chord will supply you a diminished or a diminished seventh chord. Now, what's kind of cool about this is if we take the first chord C diminished seven, you'll notice that because of this whole tone, semitone tone semitone approach, if we go through the scale, we have C, which is a chord tone from C diminished seven. We have D pulling up a semitone to the E flat. F pulling up a semitone to F sharp. G sharp pulling up a semitone to A and B pulling up a semitone to C. So I sometimes like to think of these scales as diminished chords, and everything is a semitone below wanting to pull to those notes. Now, that's true if you're starting on the first diminished chord. So we have a semitone pulling up into all of our main diminished notes. Now, if I'm starting my diminished chord on the second scale degree, now we have our semitones above each of these nodes, right? So D E flat F F sharp, right? So now we would pull down into each of these. So what it's showing you is that if you consider what sort of diminished scale you're in or where your diminished chord is situated, you can do these semitone pulls into the notes. Quite honestly, you could probably do them from above or below, not even thinking about context because you're already in an environment of tension. So we have something like C diminished seven, right? But you could also try something like and they both sound fine, and they actually end up giving you these diminished or octatonic scales. So where do we end up using this whole half diminished scale when we're improvising? Well, you use it on a diminished chord. If you're seeing in a piece of music a C diminished seventh chord, try using this C, whole half diminished scale. That's the scale you would try out if you're improvising or creating a melody in that moment of seeing a fully diminished seventh chord. So we've talked about how you can go through every single note of a diminished scale and pull out diminished seventh or regular diminished chords. And you can also start to approach diminished chords by these semitone sidesteps based on the notes that we get from these scales. Now, there is other harmony that we can extract out of these scales. It gets very complex. We're going to start to dive into that more later within the course, but in our next class, we're going to talk about the half whole diminished scale, and I'll see you there. 7. The Half Whole Diminished Scale: Alright, so now we're talking about the half whole diminished scale. So the half hole diminished scale, you could probably already guess works a lot like the whole half, but this time we're going up a semitone first and then a tone, or in other words, half step, whole step, half step, whole step. So on C, it looks something like this. C, C sharp, D sharp, E, F sharp, G, A, B flat, and then we're back to C. It's a very fun sounding scale. It's even used in the Simpsons theme song. Tell me if you recognize this. Right? So into that second section, Danny Elfman was using this scale as a sort of modulator. But I digress. I just wanted to show you that you've heard this scale before somewhere most likely. But just like our last scale, if I go up through every single note and I go up a skip, a skip, a skip, I get a diminished seventh chord. Skip, skip skip, I get a diminished seventh chord. So, again, this scale is going to pull out tons of diminished seventh shapes from every single note within that scale. But in this case, our home based diminished seventh chord, C diminished seven, in this case, is going to have semitone approach notes above each of the notes within that chord. It's fun if you start to sort of play through these but not consecutive. So instead of playing the C, the E flat, the F sharp, the A, something like C F sharp, E A, right? It's a fun little thing you can try if you're improvising or wanting to sort of twist and turn a sound around this diminished sound. So where do we end up using this diminished scale when we're improvising or creating melodies? This time, it's not going to be on a diminished seventh chord. In fact, you would try this over top of a dominant seventh chord with a flat nine. Allow me to explain. If I'm in C minor, and I'm going through all the different three note chords that are available. Let's say it's harmonic minor, so we have a B natural. On the fifth chord, I get a G dominant chord. And if I continue to go up and an extra skip, I end up getting a G dominant seventh and then a G dominant seven, flat nine. Flat nine basically is telling me that I've gone up an octave, right? There's our octave eight. If I go up a tone, that's a nine. So if we flatten it from there, in other words, up a semitone from the octave, that's a flat nine. So here is G dominant seven flat nine. If I take out the G, I end up getting a B diminished seven chord on these top notes. And if you think about it, from B to C, our home key is C, that's a semitone to Sart. And a tone to D and then a semitone to E flat, and then a tone to F. So right off the bat, this is telling us that the whole half is going to be the better scale to use in this environment. Now, you could also try this half hole diminished scale over a regular dominant chord, but it'll sound even more convincing if you're doing it over a dominant seven flat nine. So here's the sound. Let's say I have C dominant seven. I'm not going to play the flat nine for now because I'm not going to rework the voicing, but C dominant seven. He was in C major or C Lydian, technically. And then once he played this scale, it functioned kind of like a dominant seventh chord, and it would take him down to F. Also, really feel free to play around with all the diminished shapes available. I talked about how every single note from that scale can be a diminished seventh chord or a diminished chord. So you could try something like lineating all of the diminished chords available within that key it could give you some fun runs, whether you're a horn player or just wanting to play something fun and flashy on the keys. So there it is the half whole diminished scale in terms of how you find the notes, how it functions, where you can use it to improvise, or create melodies. So that's it for this class. In our next class, we're going to talk about other ways of extracting harmony from this scale. Things are going to get pretty cinematic. I'll see you there. 8. Extracting Harmony From Half Whole Diminished: And Alright, we're about to get some pretty cinematic sounds using the half whole diminished scale and extracting harmony while sort of doing some small adjustments to what we talked about before, before we were only getting diminished chords, but no different than the substitutions we talked about earlier, we can make some small adjustments within which notes we choose from the scale to also get some other chords available. Allow me to explain. We talked about how the C, half hole diminished scale ends up giving us a bunch of diminished seventh chords that we can pull out of that scale. But let's go through a little bit slower. If I go from C up a skip and then up a skip again. Just as a three note chord, we get a diminished chord. But what if I pulled that top note? Instead of skipping a note, I go up one extra note. Now I have a C minor chord. I could do the same thing, but instead of on the top of the chord, skipping an extra note, I could start that way. In other words, C, skip a note plus one, and then skip a note. I have access to a C major chord. And you'll notice I'm not playing any notes outside of that scale. C diminished is available based on this set of notes. C minor is available based on this set of notes, and C major is available based on this set of notes. So for this first note of the scale, if we're focused on minor chords to start, I would go skip and then skip two notes, and I get my C minor chord. Now the next note of the scale, C sharp, if I go skip and then I skip two notes again, I actually get a major chord in first inversion. However, if I go skip two and then skip one, I get a minor chord in second inversion. So in other words, if you wanted to extract only the minor chords from this scale, you would end up getting C minor, and then on the next note, C sharp, you get a second inversion of some chord like F sharp minor. The next chord is going to be E flat minor. As we're moving up higher, we end up getting A minor, F sharp minor, C minor, A minor, E flat minor, and then back to C minor. Every second chord was root position. So the diminished chord that we outlined the main diminished chord gives us all minor chords. And we hear this a lot in cinema, like the old X Men movies, for example, use this progression quite a bit. It sounds something like C minor, E flat minor, F sharp minor, A minor, and back to C. But if you wanted to fill in the chords in between those chords using that diminished scale, you end up getting some chords that are inverted. Again, C minor. If I wanted C sharp minor, I can't get that because Skip a note. I'm pulling out G sharp, which is not from this scale. But again, if I was to go up not one skip but two skips, and then up a skip, I get F sharp minor. I would just say, Take your time with it. When I first learned it, I was confused. I'm like, Okay, so we can have C diminished or C minor or C major. And then there's all these inversions. First, start off by understanding that every chord within this scale can be diminished. Second, the four main notes of that chord supply you major or minor chords. So C minor, E flat minor, F sharp minor, A minor or C major, E flat major, F sharp major, A major. Now, we hadn't mentioned that yet, but I kind of did, in a way. If you think about it, C up a skip up two skips gives us C minor. Then we talked about how if I go from the start up two skips and then up one Skip I get C major. The same way C minor is available, C major is available. The same way E flat minor is available. If I go up one skip then two, E flat major is available if I go up two skips then one. All of the notes from that main diminished seventh chord can supply minor sounds or major sounds. Once you understand that, that's half the battle. You end up getting inversions when you're playing around with the notes that are not the main diminished seventh chord. So we have C diminished seven, but this next chord, C Sharp diminished seven is going to give us the inversions. A great way to demonstrate this is to move through the scale. Using only the minor chords or only the major chords, you're going to get some root positions and you're going to get some inversions. Think of it this way. We start with C major. I have these big Cs on the outside, and these outside notes are going to run through the scale. I need to fill things in between so that we have this major chord. Next note is C sharp, which is in our F major chord. Remember, we only have C major, E flat major F sharp major and A major available. So again, C major, F sharp major. E flat major A major. F sharp major C major, A major E flat major, and then back to C. It gives us a root position. It gives us a second inversion based on this bottom base note, root position. Second inversion, root position, second inversion, root position, second inversion, root position. If you're a cinematic composer and you have some sort of run going through these diminished scales, you understand how you could supply a particular sound in the harmony. It also works the same way for the minor chords. You would have C minor root position, F sharp minor second inversion, E flat minor, A minor second inversion, F sharp minor root position, C minor second inversion. A minor root position, E flat minor second inversion, and then back to C minor. So whether you're taking the notes from this initial diminished seventh chord and pulling out all the minor chords or all the major chords, that's a great way to get used to this. And then if you're wondering, how do I fill out the full scale? That's where inversions of these chords are also going to be very handy. So we had this C sharp major with C in the base, and then the C sharp base note gave us F sharp major chord. Now, we could also have this D sharp coming up next or E flat. We get a E flat major root position chord. What's a tritone away from E flat. It's A. So this E supplies our A major chord. So it keeps doing these sort of tritone jumps, which is part of the reason you get this very cinematic sound. Tritone jumps within progressions get used all the time in cinema. So another approach to this is if we're starting on C major, and I'm moving up a semitone to my next note in this scale, it doesn't only supply F sharp major. There's another major chord available to us currently that also has a C sharp, and it is the A major chord. So now we're thinking of the harmony being sort of down a minor third. So C major, A major first inversion. Instead of second inversion, F sharp, we get a first inversion, A. E flat major, first inversion C. F sharp major, first inversion E flat. A major, first inversion F sharp major, and then back to C. So we can think of the harmony as these sort of tritone jumps or minor third jumps. But ultimately, at some point, you can also start to mix up the major and minor chords. You're not bound to only play major chords. You can go through this scale mixing it as well, too. Let's say we have C major to F sharp minor. E flat major to A minor. So you can really start to play around with this, but I promise you it will always give you a very cinematic sound, a sort of contemporary orchestral sound. And if you want to really dive deep into listening to some music that uses this sound quite a bit, I would say check out Mahler and Holst. They're going to be a great place to start to hear this diminished harmony and to hear just how much it influenced one of our favorite composers today, John Williams. So that's it for extracting harmony from this half whole diminished scale. The next class is still going to be pretty theoretical, but we're going to take it down a little bit, to me, this is probably the most complex version of understanding diminished harmony, but I wanted to make sure that I didn't put it as the last class so you're left confused. Let's start to wind things down slowly. I'll catch you in the next class where we're going to talk about diminished chord resolutions. I'll see you there. 9. Diminished Chord Resolutions: Let's get talking about diminished chord resolutions. If we're back in our C harmonic minor environment, we talked about how we have access to this B diminished seventh chord, and it wants to pull up a semitone to C minor. We've also talked about how this works in the major key. So B diminished seven with this note that's out of key, but we're still going to allow ourselves to play. It can pull to C major. So safe to say a diminished chord tends to want to pull up a semitone to a minor chord or as a secondary option, a major chord. But if B diminished seventh gives us D diminished seventh, F diminished seventh, and a flat diminished seventh, then couldn't we say that any of those diminished chords could also pull up a semitone to a minor or a major chord? After all, D diminished seventh is still a diminished seventh chord, and aren't they supposed to pull up one semitone? Well, let's take a look at what all these resolutions might look like. So D diminished seven can pull up one semitone to E flat minor or E flat major. What's cool about E flat major is that it's actually the relative major key of C minor. So that two chord, D diminished seven pulling up to E flat major is a great example of where a diminished chord would want to pull to that major sound. So D diminished seven pulls up a semitone to either of those options. F diminished seven, the next diminished seventh chord within this set of diminished chords that are available, pulls up to F sharp minor or F sharp major. Very distant keys from our original C key. So we were in C major. Now we're using F diminished seven to pull into F sharp major. That's a very distant key. No sharps, no flats to six sharps. Is. And if we take the A flat, it's going to pull up to either A minor or it's going to pull up to a major. A minor might make a little more sense because C minor our main key, the parallel key is C major, and the relative key of C major is A minor. So it's kind of two steps of thought to get there. But the main point here is to make the connection that these diminished seventh chords pull up one semitone. So when I'm in C minor, I have this B diminished seventh chord, and it pulls me to C E flat, F sharp, or A. Do you recognize those notes? From the last class, we talked about how the half hole scale, C, in this case, half whole gives us C E flat, F sharp and A as diminished chords, minor chords or major chords. It's the same roots as the last class. This time we're just coming at it from a different angle. So there's eight possible resolutions. So B diminished seven can pull us to C minor C major, E flat, minor, E flat major, F sharp minor, F sharp major or A minor and A major. But here's the other thing. A major or minor chord can instantly turn into a diminished. Because we've talked about these ideas of substitutions. When I'm in C minor, we said that the A flat major chord could be substituted for A flat diminished, and the F minor chord could be substituted for F diminished. So when we were in C minor, we talked about how the A flat major chord could be substituted for A flat diminished seven, or the F minor chord could be substituted for F diminished seven. So in other words, if I can play a flat major and then on the spot, choose the substitution, doesn't that mean I can change a major chord to a diminished chord? And in the example of C minor to F minor, one to four in the key of C minor, I can substitute this F minor for F diminished seven, doesn't that mean that a minor chord could change into a diminished chord on the spot? The important thing here is to understand its function. So if I'm in C major and I all of a sudden change this cord to a C diminished seven, it's kind of acting as that A flat did, the flat six now flat six diminished seven. So I know this is getting pretty theoretical, but bear with me here. C major, we change it to C diminished seven. Now this is a flat six chord. Be a flat six of E. So I would now make this cord five. So B dominant takes us to E. So flat 65, one. So C major is our key. I want to move to E minor so I can make this diminished flat 651. But also on a really simple route I'm playing C major. I'm playing C diminished seven, T E flat can pull up a semitone to E or D sharp pulls to E, whatever you want to call them. But we have this note that is available to pull up a semitone. Like we talked about before, any of these four notes can pull up one semitone. The important thing here to note is that we've sort of changed flat 651, we changed this diminished chord very slightly to create a dominant sound. This is why you're taking this course. Diminished harmony is intense. And I'm only kind of scratching the surface. Like, I mean, you can really create a whole book. You can probably do a 400 page book on this stuff. I want to give you the stuff that's quickly executable and stuff that you can compartmentalize and learn really deeply. All of this stuff, you should take one nugget and spend a week, two weeks, a month on it to really, truly make it your own. That's what I did. I would find one diminished trick that a composer used. I would get obsessed with it, just so you know, it was usually Chopin. I would get obsessed with it. I would apply it so that as I'm improvising or as I'm composing, that trick is available to me. Anyway, I digress. We talked about major switching to diminished seven, and now it functions as a flat six chord. Flat six, five, one could take you to a new key. Do you remember when we had a minor chord and changed it to a diminished chord, what is this diminished chord functioning as? Well we talked about how in C minor, it was the four chord. F minor, that can be changed to F diminished seven. So when I'm playing a C minor chord, let's say I'm in the key of C minor. I'm playing my one chord. I change it to a diminished seventh chord. Now it's the four of which key O G. So G up a fourth is C. So C is the four of G. So we could play something like four, five, one to get to G minor. So I'm in C minor, C diminished, D dominant. To G minor. See how smooth that is? And again, if I look at C diminished seventh, G is one of the keys that I could pull up a semitone two. So I could simply go C minor, C diminished seven to G. But if you think of it in context of C minor, C diminished seven is now the four of which key, it's G. So let's throw a dominant chord to really pull us there smoothly, or if you simply want to extend the harmony a little bit. Switching on a dime to a diminished chord is a little bit jarring, so I like to smooth out the transition a little bit of where that chord wants to take me. If a major chord can switch to a diminished chord, and we can understand why that makes sense, and a minor chord can switch to a diminished chord, we can understand why that makes sense, then the opposite would be true as well. A diminished chord going to a major or a diminished chord going to a minor chord makes sense because these are substitutions we're thinking of. Remember, we were in C minor. A flat major was the flat six chord, and I said we could change that diminished. Who's to say we couldn't go from C minor to a flat diminished first and then to a flat major? There's an example of where a diminished chord can pull to a major chord. It's also true for F minor. We could have instead of the one to a four and then the four substitution. We could go from a one to the four substitution and then to the four. Diminished chord, in some cases could pull straight from diminished to major or straight from diminished to minor, if you're thinking about them in context. When we're going from diminished to a major sound, it functions as a flat six of a minor key, and when we're going from diminished to minor, it's functioning as the four from a minor key. So when we were talking about this B diminished seventh chord, resolving to C minor C major, E flat minor E flat major, F sharp minor F sharp major and A minor A major, it can also resolve to a B minor or a B major. But from there, it wants to move somewhere. So we have B diminished seven to B minor, this is a four chord of F sharp, our next home key. So listen to this sound B diminished. B minor, four, five, one. We could try the flat six where we go diminished to major flat six, five, one. But at the end of the day, however you're thinking about these sort of shifts, you're always pulling into these same keys. Even when we were going B diminished to B major or B diminished to B minor, we were still pulling to one of those four destination keys. Remember I said B diminished seven pulls up a semitone from any one of those notes. It's like, no matter what path you take, you always end up resolving to one of those four keys major or minor. So to summarize, if you take anything out of this class, here it is. Easy PZ. A diminished seventh chord can pull up a semitone from any one of these notes to a major or a minor chord, or it can shift, so B diminished seven could be a B minor or a B major. You just have to understand how it wants to function from that moment forward. Like I said in the last class, this class is a little bit easier, theoretically, I think, but by a very small margin, right? These are two pretty dense classes. We're going to sort of extend this topic into the next class and talk about diminished modulations. It kind of happened organically within this class. Again, this is why I wanted to compartmentalize this course into more mini classes because it's easy to have this information bleed over. But when I was talking about all the ways that these diminished chords want to resolve, they are effectively modulating. I'm going to explain that term a little bit more in the next class, as well as dive a little bit deeper into these modulations. I'll see you there. 10. Diminished Modulations: So let's get talking about diminished modulations. In the last class, we talked about where these diminished chords want to pull to. Any note from a diminished seventh chord can pull up a semiton to a major or a minor chord, or the root can change from a diminished to a minor or diminished to a major. You just have to understand how it wants to function from that point forward. That was all covered in the last class. But now let's talk a little bit about what a modulation is. Imagine you're playing a symphony. You're Beethoven, you've created the symphony and you start it in C major. How long can you play in C Major before it gets kind of boring, before your audience wants to hear a little twist and turn. It's like a story line. You have to throw these pivots into stories. If it's happy, make it sad or spooky all of a sudden. After all, some of the best horror movies have some great comedic moments in them so that it's juxtapose before that next jump scare. Modulations allow you to sort of twist the harmony to take you to a new destination. So I'm starting my symphony in C major, but maybe a section later on is in G minor, and that continues for a while before I have a section in E flat major, and then eventually I come back to C major. Think of a modulation not as a short rest stop, but rather totally shifting into a new key for a while before eventually moving somewhere else. Now, one of our best modulators are dominant seventh chords. These chords want to fall down a fifth to a new major or minor key. If you're not familiar with dominant seventh chords, they're major chords with a tone below the octave. This is a flat seven or a minor seven, and these chords, as mentioned, want to fall a fifth to either minor or major. So C major, let's say I'm in the key of C major playing a simple progression. Now I'm going to change this one to a C dominant chord. That takes me to F, let's say F major. Now it feels like I'm in F major, and I could play in that key for as long as I would like before potentially returning back to C or going somewhere else. While diminished chords work very similar. If you look at a dominant seventh chord, you only have to change the bottom note by a semitone up, and then you get a diminished seventh chord. What's cool about this is we talked about how C dominant wants to fall a fifth to F. Once I've created this diminished seventh chord, we've talked about how the diminished seventh chord, any of these notes can pull up a semitone. Well, look at that. E can pull up a semitone to F, so it brings us into the same destination. So you can do these moves like a dominant chord, change it diminished, and still pull to that same destination that the dominant chord would have wanted to go to. It's also true inversely, where you have a diminished seventh chord, pull the bottom note down a semitone, and then it drops a fifth to either a major or a minor resolution. In the case of that example, C Sharp diminished seven, we know that C Sharp can pull to D or E can pull to F, or G can pull to G sharp, or B flat can pull to B. Well, E to F was one of our options. So let's say C Sharp diminished seven, wants to take us to F. We can do C sharp diminished seven, drop the bottom note, and then follow a fifth to F, the same. You might want to watch this last section a few times, but the thing I'm trying to show you is that dominant resolutions and diminished resolutions are very interrelated. So their modulations of moving into a new key are also related. So here's where it gets really crazy. Check this out. C diminished seven is the chord we're going to work with. What are the four main notes that we can resolve to from here? I'll give you a second. Here's our four notes. A semitone above any one of these notes. C can go to C sharp, major or minor. D sharp can go to E, major or minor, F sharp to G and A to B flat, same idea. Now, if we change any one of these four notes by a semitone, we can get four different dominant seventh chords, and those chords want to pull down a fifth to the same destinations. What? That sounds crazy. Sounds complex. Let's break it down. First, let's talk about this C sharp as our first resolution point. C diminished seven can pull to C sharp minor, and C diminished seven can pull to C sharp major. But if I change one little note, I can access the dominant chord for this destination. What's up a fifth from C sharp or D flat? It's a flat. So check this out. If I take the top note of this diminished seventh chord and lower it a semitone, I actually get a flat, dominant seven first inversion. So where would this take me down a fifth to C sharp or D flat? Again, major or minor, your choice. So now we kind of have this diminished to a dominant to a resolution. The next note that we could resolve to is E. E up a fifth is B. So how can I change this shape to make it a B dominant seventh? Just lower the bottom note down a semitone. So C diminished seven, B dominant seven to E. Whether you want to go diminished straight to E, which works or extend it a little bit, with a five to a one based on these small movements, both are very much available. The next key available is G. If I lower the second note by a semitone, I get D dominant seven. That is the five of G, and it pulls me to G. The last destination up a semitone from A is this B flat. If I lower the third note, F sharp down to F, I get an F dominant seventh chord, second inversion, and that's going to resolve down to B flat. Again, minor or major really it's your choice. So as an overview, in terms of modulating, we talked about how this C diminished seventh chord wants to pull up a semitone to any one of these other four keys, C sharp, E, G or B flat. But just using a diminished chord to pull out of nowhere to those keys can be a little bit jarring. I'll give you an example, C minor, B diminished seven. Let's just move back and forth between those. I'm in the key of C minor, and I'm going to play that seventh chord available, which is B diminished seven. Now I'm going to pull it to one of the other available keys. B diminished seven could pull to, for example, F sharp F op semitone. Let's try that. We're in C minor. C minor. Let's keep it going. Now we're going to pull. Wow. It works, but it's, like, out of nowhere. So instead, you can take the diminished seventh chord and prepare the dominant sound to pull to that new key. Now we have C minor, B diminished seven. C minor, B diminished seven. Let's lower the D down a semitone. And then it pulls us into F sharp minor a little bit more smoothly. From there, you can stay in F Sharp Minor. You are fully modulated until you want to move to another key. So think of a main train track. And there's some other train tracks that are kind of spaced out a little bit farther out that your train can also fit in. But to get to those other tracks, you have to move through a track in between. So let's say you're on track zero, and you want to get to track two. You have to get through track one and then over to track two. You're in the key of C major. You're using a diminished chord to pull over to that next train track. Essentially, that's kind of summarizing modulations as a whole. That train track in between doesn't have to be a diminished seventh chord, but this is a class on diminished chord, so in this case, it is. It could be a dominant chord, it could be a minor six chord. Whatever it is, it then pulls you to that next track. So if you're curious about modulations and this is intriguing you and you want to learn a little bit more, I have a whole course on harmonic modulations. Feel free to check it out. But if you're just here for the diminished stuff, I think this class summarized quite well how diminished chords can be used to modulate and also how they relate to dominant chords and how that can help us smooth out those modulations. Now, I'll be honest, this was originally going to be two classes. I was going to talk about simply how diminished chords can modulate up a semitone to any of these keys. And another class was going to talk about the relationship between diminished chords and Dominic chords. But I think ultimately it made more sense to put these two together just because they're so related to one another. As a result, if this felt like a bit of a more dense class, it's 'cause it is two sort of fused together. So make sure you're going through this class a few extra times to help yourself really digest this material. The next class is going to be much smaller and much easier. We've gone through most of the dense theory at this point, in the next class, we're going to talk about how diminished seventh chords were used in classical and romantic music and how we can take this harmonic concept and fuse it with our melodies. I'll see you there. 11. Diminished in Late Classical & Romantic Harmony: Let's get talking about diminished harmony in the late classical and romantic eras. Now, there's a specific trick that I have in mind that I want to share with you that starts to connect diminished harmony with melodies that also work well with that diminished harmony. So if you recall, when we were in C minor C harmonic minor, the seventh, second, fourth, and flat six scale degrees were the four notes that made up our diminished chord. So what's kind of cool is if at any point you have one of these four notes in your melody, there's something you can do with your diminished harmony to accommodate that melody note. Allow me to explain. When we have in the left hand a fully diminished seventh chord, taking either of these middle notes, in this case, D or F and getting rid of it and moving it up one octave, puts that note into the melody, and now we don't have it doubled in the left hand. Usually, we don't want to have that note in the harmony because you're going to get more intervals like tritones and just more dissonance. So this way, we keep things relatively dissonant, but we're just spreading out the voicing in an appropriate way. So here's our four notes. Whether we're taking F, up the octave or D, we will omit that note from the left hand. Now, B and A flat are also options, but you would start to move through inversions of the diminished chord. In other words, moving to the other diminished chords that are available, D diminished F diminished A flat diminished, which is the same as B diminished seven, first inversion, second inversion, third inversion, and you would extract one of the middle notes from that chord. So now we could have the F up here or the A flat. On the next chord, we could have A flat, getting rid of it in the left hand or B, getting rid of it in the left hand. And lastly, we can have voice from the flat six this time, the B or the D. So as you're going through and playing a melody in a harmonic minor key, if your melody note is one of these four notes, try creating this diminished chord in your left hand, omitting that note, and you'll find that it just gives you more of that late classical and romantic era sound. Let's say we have something like 15, five, one. I'm going to go to the four. Allow me to explain. So when I went to this four, I was playing B diminished seven in my left hand, omitting scale degree four. So this was a substitute for what I might have otherwise played as a minor four chord. We talked about how this four chord or the diminished version of that four chord is a great substitution. But now I'm thinking of this four chord, more so in an inversion so that I can accommodate that melody note, the fourth scale degree. I'm still kind of I'm not really thinking B diminished seven. I'm thinking F diminished seven as a substitute chord, but again, getting rid of the F and putting it up into the melody. There's another one there, so we have this A flat, and I'm playing the fully diminished seventh chord minus the A flat. And then, again, lots of ones and fives to sort of accommodate testing this environment out. Now, in a major key, you're not going to get that flat six, but you still will get the seven, two, and four quite often in your melodies. I'm not saying you'll never get this flat six. If anything, you would think of it as a sharp five, most likely in something like an E major or E dominant chord, taking you, in this case, to the relative minor, A minor. I digress. For now, I would say, G sharp A flat, kind of leave it alone until you feel like you're ready to kind of buff things up a little bit from a basic starting point. But for now, keep it basic. So let's say we have a melody that goes On this B, when I come down to it, I'm going to play a B diminished seven chord situated in a way where B is one of the middle notes. So inverting it. In this case, it looks like after diminished seven. Again, this is all kind of the same stuff, right? After diminish seven is B diminished seven, second inversion, whatever you want to call it. So we have this B in the melody, and then here's our diminished chord omitting the B. So it ends up sounding like this. What I love about this sound is that you're also really close to a minor six chord, one of my favorite versions of a four chord. So you could have something like major one to a diminished four and then the four minus six, and then resolve back to the one. There's lots of ways you can start to play around with all these different modulations and harmonic shifts. Again, though, what I want to show you is that diminished chords are very close to so many other shapes. We've talked about how they're close to dominant shapes. They're also close to minus six shapes. One of our classes will cover more of these sort of connected shapes, but I just wanted to mention that's another fun thing you could try. So if you're in a major key, whether your Mladeno is the seven, the two, or the four, you can play around with the diminished shapes and get rid of the seven, two or four from the middle to accommodate this wider spread keeping the melody and the harmony interrelated. That's the main thing I wanted to cover in this class, the idea of omitting a note from the chord, especially one of the two middle notes and having that as a melody note. Since your scale degrees are always seven, two, four, and flat six, when you're working with the home key diminished seventh chord, then your melody notes, when you have either four of those, consider diminished harmony as an option to sort of case that note. That's it for this class. I'll catch you in the next one where we're going to talk about diminished passing chords. I'll see you there. 12. Diminished Passing Chords: Let's get talking about diminished passing chords. This class is a little bit easier. Again, we're going to connect things to dominant sevens dominant and diminished are very related. But I mentioned a while back that you can think of harmony, like the body of a song, and diminished would be all the veins and nerves running between the main muscle tissue. Here's a great example of that. If I play through all of the chords available in C major, I haven't touched any of these black notes. So what if I did want to play a chord on one of those black notes? A great option would be a diminished chord or even fully diminished seventh. Let's check it out. C major, C Sharp diminished seventh. D minor. D sharp, diminished seven, E minor, which is beside F major. You could even if you want, you could jump to F major, but you could even switch it E diminished to pull it up to F, F sharp diminished, pulls to G, G sharp diminished, pulls to A minor. This one's a bit odd. B flat diminished, pulls us up to the either B diminished or B minus seven, flat five, which then takes us back to C. So there's this sense of prolonged tension when you start to reach this sort of seventh scale degree. But this part and this part and this part and this part and this part all sound great. So for now, I would say, avoid the flat seven and the seven until you've mastered the lower part of this scale and all of those diminished passing chords. These are ultimately chromatic passing chords. There are notes that are a semitone in between other important chords. We're moving things by semitones, and in between those important diatonic chords, the ones true to the key, we're playing diminished seventh chords. Now, what's interesting is I've played C major, and then I've played C Sharp diminished seven. Where does C Sharp diminished seven want to go? It wants to go up a semi tone. So that's why it's able to pull us up each time in a way that sounds resolved. If you wanted to get adventurous, you could play something like C major, C diminished seven to D major and sort of do these little twists and turns because ultimately, a diminished seventh chord can pull up to a minor chord or to a major chord. So you can do these fun little switch ups. Diminished chords really do offer a lot of sort of modulations, switching keys, changing the tonality. So feel free to play around with it a bit. Now, I mentioned that these also relate to dominant seventh chords. C Sharp, diminished seven wants to go to D minor or some sort of Dcord, right? But again, if we just alter one of these notes, the top note down a semitone, you can see, have A dominant seven in first inversion. Where does A dominant seven want to go? Dominant tend to want to fall a fifth, in this case, to D, so you can have this diminished, resolve one note down, and then pull up. Diminished, resolve one note down, and then pull up. Diminished, top note down, pull up. And you can try that as little extensions on each of these diminished passing chords. Another thing you can try is keeping it fully diminished. In your left hand, you're going to play something like C major to start, C sharp fully diminished. Now drop the left hand to A. While keeping this fully diminished seventh chord, what you have here is an A dominant seven flat nine. A flat nine is just a fun color to add. It tends to want to resolve to a minor sound, but it does not have to. So now we have A dominant seven flat nine. A dominant seven falls to D, so then you go to D minor. It ends up sounding like C major, C sharp diminished seven, a seven flat nine to D minor. D sharp diminished seven, B seven, flat nine. To E minor, E diminished seven, C seven flat nine to F major, F sharp diminished seven, D seven flat nine, to G major. G sharp diminished seven, D seven flat nine, to A minor. And then it gets kind of squirrely up in the top, like I had mentioned. But you can see there's those two ways that you can play around with connecting the diminished sound to the dominant. Step one is really just every single note in between the cracks of your scale, you would play as a diminished chord. Again, the third scale degree, you can choose to go from E minor to F major or extend that diminished sound to pull up to F major. From there, you can try these little shifts. Top note down a semitone gives you the dominant sound before the resolution. Can try changing the base note so that it falls to the note that completes the dominant sound before resolving. But again, it resolves to the same spot. So that's it for this class diminished passing chords. There's tons of dominant alterations that we were playing around with, but start with the basics and expand from there. If you're ever not sure what chord to play in between the cracks of the notes that are in your scale, try either diminished chords or some of these dominant tricks that I've given you. 13. Minor 7 Flat 5 Chords: Now, I want to do a small class outlining the minor seven flat five chord, AKA, the half diminished chord. When we're in a major key and we're moving up through all these four note chords, we end up getting on the seventh scale degree, a minor seven flat five or half diminished seven chord. What these are is they look a lot like a minor chord with a tone below the octave. This is a minor seven chord. But then we take the fifth, in this case, half sharp and we flatten it. We lower it one semitone. Whether it's to white or to black, doesn't matter, down one semitone. Now we have a minor seven flat five. As I mentioned, it's also called a half diminished seven chord because it is diminished on the bottom three notes, but having a minor seventh, a tone below the octave, as opposed to a diminished seven, which is a minor third or three semitones below the octave, it's not fully diminished. It's diminished with a minor seven, so half diminished seven, which looks like a degrees sine and a slash through it, little tiny circle diagonal slash. Now you can also find this chord in the natural minor scale. If I'm going through A natural minor, also all whites, it was the second chord. So we can think of this as the seventh chord of C major, or we can think of it as the second chord of A natural minor. You're more often to see it functioning as the two in a minor key. This especially gets reinforced in jazz harmony, where 25, one is the main progression. So in C major, we would have D minor seven, G dominant seven, C major seven, two, five, one, four note chords built off of the second scale degree, fifth scale degree, and the first scale degree. In A minor, we get something very similar with a small change. B minus seven flat five is our two. E minus seven is our five. We're going to change it to E dominant seven and steal a note from the harmonic minor scale, in this case, the G sharp. So we had two minus seven flat five, five, dominant seven, one A minor seven. The five in both cases was dominant. In A minor, it was an E dominant seven. In C major, it was a G dominant seven, but everything else had some small changes throughout. Now, in the major key, this seven chord, the B minor seven flat five doesn't pull up to C major as well as a fully diminished seven chord. It just has to do with all these notes and the way they want to resolve. If you think about this A, it resolves to this G in the C chord, but this A flat resolving to the G, has a little bit more tension resolution. I think of these semitone resolutions versus tone resolutions as magnetic attraction. If there is a magnet and I place a needle over here and it's vibrating a little bit like it wants to move over, you'll feel that tension. But what if I now place the needle here? It's going to really snap over to that magnet. So the way that these notes want to move between cords is really important. Semitons have a huge attraction when they're pulling from one cord to the next. And take a look at this. We have B going to C, that's a semitone wanting to move. A flat going to G, that's a semitone wanting to move. F going to E, that's a semitone wanting to move, and this D sort of gets split out a tone either way. There's a lot of semitones wanting to pull us to that resolution. All this is to say the seven chord, B minus seven, flat five does not function as well as a fully diminished seven chord in terms of resolving up a semitone to that one chord. But in a minor key, we're going to see a particular function for this chord. Again, it's a two chord within a 251 chord progression. So one thing we could consider is if we're in a major key and I'm playing around. I mean, this would not be a great progression, but let's say I'm moving up through my cords. Once I reach this seventh chord, instead of resolving to C, which would sound like this. Sounds fine, but you could once you hit this chord, set up that 251 of A minor. Check it out. That feels like it functions better. So for now, what I would say is for the minor seven flat five, think of it more as existing within a minor environment. It doesn't doesn't only exist there. But as a starting point, you want to kind of oversaturate some theoretical ideas until you're bored with them or you just fully understand them and then kind of learn their secondary functions. For me, I would say that the minor seven flat five has more of a primary function within a minor key. So that is the minor seven flat five chord. The diminished scales don't work particularly well with it. If you're going to use one, I would use the whole half diminished scale, but there still is some conflict as you reach into the upper notes of that scale. Technically, you would either play Locrian or Locrian Sharp two outside of the context of this course, but I wanted to let you know that if you're someone learning jazz piano or wanting to improvise or create a melody over this sound, in short, when you're on that seventh scale degree of C major, if you were to consider a scale, B to B, all white notes, that is Locrian. You can also sharpen the second note and move through this way. If you watch, we get this tone semitone, tone semitone, tone, and this is where it breaks, tone, tone. So the Locrian sharp two tends to be a great sound, but you can also play around with the Lokean mode as well. Again, I was reluctant to even mention this because I think it's out of context, but there it is, if you want to improvise over top of that chord, look more into those scales. So that's it. For this class on the minor seven flat five AKA, half diminished seventh chord, and how it functions harmonically. I'll catch you where we talk more about altering chords to and from diminished shapes. I'll see you there. 14. Altering Chords TO or FROM Diminished: Alright, so I've already done some discussing about how we can change dominant chords to diminished shapes and vice versa, but I wanted to have one class that sort of consolidates this information and introduces a couple of other chord shapes as well. Let's start with a major seventh chord. Quite simply, if you take the bottom note and raise it up a semitone, you get a diminished seventh chord, and from there, you can choose to modulate in any of the ways that we've previously discussed. So it's really common to see in romantic music and late classical music, certain shapes, maybe not so much major seven, but certain shapes out of nowhere, just having a small change, creating some tension and functioning as a modulator. So don't be afraid if you're writing a song that has a major seven chord, pull the bottom note up a semitone and then play around with modulations from there. Again, keep in mind this wants to go to D minor most, but you can play around with a semitone above any one of these notes. So you can go to D, you can go to F, A flat, or C, major or minor. It depends on how jarring you want these modulations to be, but no matter what, they'll at least kind of work. Now, with a minor seven chord, you don't get to change just one note by a semitone and find your way to a diminished seventh shape. But if you do flatten the five, you get a minor seven flat five. We talked about this chord in the last class. How does it like to function as a two of a minor key. So from here, two, five, one of some new key. So let's say I'm improvising in C minor, Now, I flatten the fifth. So that was a two, five, one of B flat when I got to that spot. So in other words, you take your one chord, which is a minus seven, and at some point you just flatten the fifth and set up that new 251 modulating you down one tone. Now, we've also talked about how a diminished seventh shape, if you flatten any one of those notes, you're going to get a dominant seven shape most likely in some sort of inversion, one of them will be a root position. So C diminished seven wants to go to the keys C sharp, up a semitone from the C, E, up a semitone from the D sharp, G, up a semitone from the F sharp, and B flat up a semitone from the A. But if I make any of those small changes of lowering one of these nodes to semitone, again, I will access some sort of dominant seven shape, which will want to follow a fifth to these same destinations. Let's check it out. C diminished seven, lower the bottom note, which is B dominant takes us to E, one of the four options we had. So C diminish seven, B dominant seven, E minor. C diminished seven, D dominant seven, to G minor. One of our other options. C diminish seven to F seven or F dominant seven to B flat minor. C diminished seven to A flat, dominant seven, to C sharp minor. So again, you can take any of these diminished seventh shapes, lower any of the notes by one semitone, which will become a dominant chord, which then wants to fall a fifth. The four options you'll have are the same options that you have for simply resolving the diminished seven chords to where they want to move to. Now, the same way we can take a minor seven shape and turn it into a minus seven flat five. We can also take a diminished seven shape, raise up the top note, and now it's a minor seven flat five. How does it want to function? As a two chord in a minor key. So we have the C diminished seven. Now we have C minor seven flat five, F dominant to B flat, two, 51. Now, what's cool is sort of like the dominant seven shapes. You can take any one of the four notes from a diminished seven chord and raise it up a semitone. And you'll get the minor seven flat five. The easiest one to see is when we take that top note up a semitone. But watch what happens if I pull C up a semitone. Now I have E flat, minus seven flat five, but it's in third inversion. This sets up 25, one of C sharp. So isn't it interesting that this C sharp E, G, and B flat destinations for the diminished seven resolutions are the same spots that you would resolve to based on the dominant tricks and also based on these minor seven flat five tricks. Same thing if I take the second note up a semitone, I have F sharp, minus seven, flat five, second inversion. There's our 25, one to E minor. Again, one of the proper destinations of this diminished seventh shape. Lastly, we're going to take the third note F sharp and raise it a semitone. Now we have A minor seven flat five first inversion. So we end up getting from this C diminished seventh shape a two, five, one of G minor. And then you can start to dive even deeper because every minor seven flat five chord is also a minor six chord in disguise, and these function as fours. So at some point, the spool of wool just gets fully unwound and everything starts to kind of bleed into each other. Do you see why I say diminished harmony sort of is the veins and the nerves? It runs between everything, and it's like this connective tissue that has so many ways of connecting our more basic functions of harmony, like major chords and minor chords as resolutions. So just keep in mind that diminished shapes with a small change can become major seven chords, minor seven flat five chords, dominant seventh chords, with a couple of changes, minor seven chords, and those chords can also very easily be changed into diminished. It works both ways. So I'd recommend if you're working on a song, try to play around with some of this stuff. When I'm improvising, I surprise myself sometimes that when I bust out some of these tricks, I don't feel like myself as a player. I feel like I'm listening to someone else. I'm almost in awe in the way that it sounds. Because, for example, I really love Moonlight sonata by Beethoven, which uses tons of diminished harmony. So for me, it has this very connected root to me as a musician, but I never fully understood the harmony until about the last five years when I started to dive deeper into it. So for me, it's still a relatively fresh sound because there's so many new ways that you can explore it. I'd recommend you do the same. Keep it simple. You don't need to do the most complex version of these alterations, but try switching up some chords. I'll give you one last example. So let's say I'm in C major and I have a basic 251, something kind of jazzy sounding. Raise the bottom note by a semitone. But instead of moving to D minor, I'm going to move to F minor. Oh, kind of cinematic and a little bit jarring, but it works because, again, this C Sharp diminished seven chord, any one of these four notes can resolve up a semitone to a major or minor chord. So while C Sharp really wants to go to D, it can also, for example, this E can pull us up to F, and you get some really interesting shifts in your harmony. So that's it. On this course on altering chords to or from diminished, I will catch you in the next class where we're going to talk about unrelated diminished chords. I'll see you there. 15. Unrelated Diminished Chords: Alright, this is kind of an extra little bonus mini class, but talking about unrelated diminished harmony, here's the trick that I sometimes use, and I think it sounds pretty cool. So let's say we're in C major, and I turn my chord to C diminished seven just to really kind of create some tension and maybe possibly modulation. Now, I want you to jump to any other diminished seventh chord. And then maybe a different one fully unrelated, and then resolve as you see fit. The idea here is that the diminished chord sort of washes out the palette of whatever key you're in. So we're in C major. Now I'm not so sure C diminished seven. So things are really washed out right now in terms of where we're supposed to resolve. There's lots of options. Let's move to another diminished seven chord, maybe G, and then D and then resolve. This is a classic case of prolonged tension. Now, where I first thought that I heard this was in Beethoven's moonlight sonata. It turns out he was doing some kind of calculated diminished chords. These are the exact ones he used. I want to make sure that I'm kind of giving some more fresh examples, but it was something like this. And then he kind of has at some point, like, a minor chord and then he's playing around with all these different diminished shapes, and I remember thinking in the moment, it just sounds like random diminished chords, and it kind of works. He is thinking about them in terms of how they function within the harmony. But I started to play around with that concept of, like, what if I just move from a diminished chord to a completely different one? It kind of works cause diminished is so tense. Think about the movie, everything everywhere all at once. It is a completely chaotic movie. You never know where it's going to go next. So wherever they do take you, you're like, Okay, I was kind of already along for this ride. Anyway. You haven't seen that movie, just consider a movie where every scene just kind of keeps randomly taking you to a new spot. You don't know what's coming next. Diminished Harmony kind of does that as well. And once you've done two, for example, like F diminished seven to G diminished seven, well, now the listeners are already going, Okay, where are we going from here? I can go to 1 million places, and then eventually takes you to some sort of a resolution. So this sort of mini class was really just to tell you that if you're playing a diminished chord, feel free to hop to another one related or unrelated. You can probably get away with about two of these diminished hops. In other words, three diminished seventh chords in a row. Before you should probably resolve it. This prolonged tension can't go on forever. If it does, you're going for a very particular sound, and you can't necessarily expect your audience to appreciate it as much as you. After all, after a lot of tension, as humans, we do love a good resolution. So that's it for this class on unrelated diminished chords. In the next class, I'm going to give you a diminished seventh chord exercise. I'll see you there. 16. Diminished Chords Exercise: Alright, so here is one of my favorite diminished seventh chord exercises. If we go up through a harmonic minor scale, three of the notes accommodate the one chord. In other words, I'm in C harmonic minor. Here is my C minor chord. So as I'm playing through the scale, C, E flat, and G are accommodated by this particular chord. All of the other notes, the D, F, A flat, and B are covered in the related diminished seventh chord, in this case, B diminished seven. Now, there's two ways that you can play through this exercise. The first way is going to be left hand only. And this is sort of going to warm you up into the full version of the exercise. Left hand thumb is going to play up through the harmonic minor scale, and the lower fingers are going to complete either a diminished seventh chord or a one chord in some type of inversion. So C is my first note. That's in the C minor chord. So I am C minor first inversion to keep the C on top. F diminished seven gives us the D on top. C minor second inversion gives us the E flat on top. A flat diminished seven gives us the F, C root position gives us the G, B diminished seven gives us the A flat. D diminished seven gives us the B, and then C minor, we have the C back on top. Without me talking, it sounds like this. The second version of this exercise, which is the full version, now your right hand is going to be moving up through the scale, and your left hand is going to accommodate that harmony. Whatever note you're playing has to be the middle note of the chord that is accommodated by that note. In other words, C is accommodated by which chord? Well, the C minor chord B diminished seven has no C. So we have a C in the melody. Here is my C minor chord. But I want this C to be in the middle of the chord. Which would be second inversion. From there, you're going to omit that note. So here's that sound of C in the melody, the C minor chord in the harmony, accommodating this middle note jumping up into the melody and being omitted in the chord. We talked about doing this with diminished chords, so we're also going to be doing that with our minor chord. So once you have this first shape, your right hand is going to move up to the second note in that scale. I'm going to move up to a diminished chord next, A flat diminished seven and omit the D that's in the melody. E flat is my next note, C minor omitting the E flat. F is my next note. B diminished omitting the F. G is my next note, C minor omitting the G. A flat is my next note. We could go D or F diminished seven omitting the A flat. Next note is B. We could also stay on the same shape and just flip which note is omitted, and then we're back to C, the same starting shape that we had to begin with. Now, remember, the idea that you can take in a diminished seventh chord either one of these middle notes and omit them and bring them up in octave means that when you're playing the notes that relate to the diminished shapes, you'll have two options. Right off the bat, we have this as our C minor starting point. In terms of this D, the second note of the scale, sure, I can go to A flat diminished seven and omit the D, but I could also go to B diminished seven and omit the D. To me, the A flat makes more sense just because it's a smaller movement in that left hand. So you ultimately get to make that decision, but I want you to try to streamline things as much as possible in terms of your voice leading. So that's it. That is two versions of the diminished seven exercise. It really outlines that in a harmonic minor scale, we're really working with two fundamental chords, the minor one and the diminished seventh chord built off the seventh scale degree or second or fourth. Or flat six. So I hope that those numbers seven, two, four, and flat six are starting to really resonate with you because you want to start to associate them with the potential of diminished harmony. As we've discussed before, we have substitutions. We have lots of options. But certainly, if this is a sound you want to explore, keep those numbers in mind. This is absolutely a course you're going to want to review. Many times, the material is quite dense I want to thank you for being here on this diminished seventh journey with me. Make sure that you're applying this stuff within your playing, within your compositions. Thank you one more time for taking this course. I'll see you in the outtro video and maybe in another course down the line. Thanks again, and I'll catch you in that outtro video. 17. Outro: Congratulations on finishing this course on diminished harmony. As you can see now, diminished harmony can go from quite basic to quite complex. Whether you're simply hoping to learn the shapes of diminished seventh chords or better understand how to use a half diminished seventh chord within a progression or even use diminished seventh chords as modulators, there's a lot of different layers of complexity in terms of how we can use these chords as composers and performers. I feel as though this course deserves a bit of an extra congratulations because this is one of the tougher ones. It really does start off kind of basic, but as you noticed, I kind of put my foot on the gas within this course because diminished harmony, no matter what way you slice it, has a lot of use cases, and it's a very involved, deep, delicious sort of sound that we can use within the palette of harmonic exploration and options. All that is to say, this course was kind of tough, so extra props to you for getting through it. Now, don't forget to go back to the class that outlines all the project details for this course because I would love for you to submit that so that I can give you some feedback and also so that you can start to understand what area of diminished harmony you like the most and how you can further explore diminished harmony in that direction. Don't forget to practice the material that I've provided. Again, I would love if my students practice a little bit every day, but aim for five days and see if that works for you. Take the material that I've given you into whatever private lessons you might be taking so that your teacher can help you improve the material, but also give you their own twist or understanding of the material provided. So feel free to sift through the courses that I've created, see if any others resonate with you, and then slowly improve those building blocks that'll help you stand out as a musician. I hope you enjoyed this course, and I'll catch you in the next one.
