Enharmonic Pentatonic

Here is a canon on an ancient Greek scale.

The enharmonic has a number of interesting forms. The one I used today is its pentatonic.

It works like this:

Two tetrachords each spanning a perfect fourth (the ratio 4:3) and connected by a whole step (9:8).

Each tetrachord contains a descending Major third and a half step.

So:

C Ab G F Db C
