Still thinking about Japanese tetrachordal theory

[thinking hard]

CEFAB [thinking even more] E-F-A is a tetrachord, and I guess I could consider B and C to be affixes (the notes are like, right next to each other). But what if you take B to be the “upper” tetrachord, then the perfect fourth would be… E, ooh you build the rest of the miyakobushi scale back to the beginning, because the tetrachord ends up B-C-E, which is, again, a miyakobushi tetrachord. Intervals are 1, 4, then 2 to change tetrachord, then again 1, 4. 1-4-2-1-4 is the miyakobushi scale.

So we could transpose Sakura to a Ryūkyū scale with… lower tetrachord E-Ab-A, upper B-Eb-E? So instead of: AAB AAB ABCBA-BAF, you'd have AAB AAB ABEbBA-BAAb? (tries it out) well that sounds off. What if we align the scales some other way, so that the intervals kinda match better:

E F A B C E 1 4 2 1 4

E Ab A B Eb E 4 1 2 4 1

[thinks harderest] well rotate it a bit and:

E>Ab F>A A>B B>Eb C>E

BBEb BBEb BEbEEbB-EbBA

Omg this kinda works hahaha I've invented the Okinawan Sakura. I invented the Deigo Deigo
