This is a work in progress…
Still in just intonation, but some notes outside the diamond.
- C 1/1 major
- F 4/3 minor
- C 28/15 major
- A 5/3 major
- B 7/4 major
C 28/15 is really close to B 15/8. 225:224 away. But the E 7/6 of C 28/15 is a perfect 5:4 above the C 28/15, and there are other 7:x rations all over the place to give it a sense of continuity. This is the first time I’ve ever ventured outside the diamond.
