Before I start, english isn't my first language, so sorry for any grammar mistakes :)

- I've decided to use the Phrygian scale.

- (1) First I started drawing the chords that are used the hole track.

  - The chords have tension at the beggining;

  - Then release after the first chord (where it has, if I am not mistaken, a Esus4);

- (2) After that, I drew the bass line.

  - Here the notes are correspond to the second note of each chord.

  - I think this had a great impact on music.

- (3) Then I make the melodies.

  - Where I circled around the notes of the chords.

  - And changed the octaves to get "more songs" playing at the same time.

- (4) Also, I added the Drums to give more rhythm.

I am new on music production, but I liked the result and I hope you like it too.

I added a link to my song on the coments.
