User:CompactStar/RST notation

RST notation is a notation for just intonation, primarily developed by CompactStar. It is an extension of 3-limit circle of fifths notation with inflections for higher primes as "ruper-"/rub-" for 5, "super-"/"sub-" for 7, "tuper-"/"tub-" for 11, going through the alphabet starting with R. After Z, it resets back to A, then B, etc. until Q. This is compatible with the common usage of "super-"/"sub-" for inflection of Pythagorean intervals by 64/63 in the 2.3.7 subgroup.
