Here is a version of the first movement of the Sonata I’ve been working on lately. It uses the same four scales derived from the Partch Tonality Diamond taken to the 31-limit.
- D1maj – take the otonality starting on 16:9 (~A#), and build a 12 note scale in the key of D major on the 10:9
- D6maj – take the utonality starting on 5:3 (~A), and build a 12 note scale in the key of D major on the 10:9
- A2maj – take the utonality starting on 5:4 (~E), and build a 12 note scale in the key of A major on the 5:3
- B2min – take the utonality starting on 5:3 (~A), and build a 12 note scale in the key of B minor on the 40:21

For each measure in the piece, I chose which of the four scales to deploy based on how well it plays the notes in the measure.
