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.
