I discovered that if I play a major scale, i.e. Ionian mode, then move through the modes with the same root note in the following order:
- Ionian
- Mixolydian
- Dorian
- Aolian
- Phrygian
- Locrian
At this point I'd next play the Lydian scale, but starting a semitone lower than the Ionian I started with earlier.
Then I'd finish on the Ionian scale starting a semitone lower than my original scale. I've sort of drifted downwards by a semitone. I've attached the snap showing what I'd play if I started in C major. But applying the same sequence of modes again means I drift down a semitone each time I reach the next Lydian scale.
I really like that each subsequent scale in the sequence of modes has one more flat than its predecessor.
Question is - what's the name of this progression?
