VERY WIP (I'll move it to the main namespace if it's finished.)
The greek letter notation is a notation scheme developed by CompactStar for just intonation up to the
Accidentals
| Prime limit | Letter | Ratio | Letter | Ratio |
|---|---|---|---|---|
| 5 | α | 81/80 | β | 80/81 |
| 7 | γ | 64/63 | δ | 63/64 |
| 11 | ε | 33/32 | ζ | 32/33 |
| 13 | η | 1053/1024 | θ | 1024/1053 |
| 17 | ι | 4131/4096 | κ | 4096/4131 |
| 19 | S | 513/512 | T | 512/513 |
| 23 | U | 736/729 | V | 729/736 |
| 29 | W | 261/256 | X | 256/261 |
| 31 | Y | 32/31 | Z | 31/32 |
For example, 5/4 is IM3 (I-major third), 7/4 is Km7 (K-minor seventh) and 11/8 is LP4 (L-perfect fourth). Above C, these would be written IE, KBb and LF respectively.
For temperaments
Letter notation can be adapted to regular temperaments simply by using the notation of the just intervals being tempered.
