Tonight’s song/idea is titled, “Spiral” and is in the key of D# Major (C Aeolian Mode).

If you’re not familiar with modes, or if modes are confusing to you, then maybe this explanation will help.

The notes of the D# Major scale are: D#, F, G, G#, A#, C, and D. Any note of the major scale can be the focus note (or mode) of your chord progressions. The mode is the note that your chord progressions resolve to.

The modes of all major scales are:

  1. Ionian (Major Scale)
  2. Dorian
  3. Phrygian
  4. Lydian
  5. Mixolydian
  6. Aeolian (Natural minor scale)
  7. Locrian

Since “Spiral” focuses on the C note and the note C is the 6th note of the D# Major scale, I’m playing in C Aeolian. The Aeolian mode is also known as the Natural Minor scale.

To help clarify further, if I focus on the note “F” which is the 2nd note of the D# Major scale, I would be playing in F Dorian. Focusing on the note G means I’m playing in G Phrygian and so on.*
