Does LucyTuning match the rules of music theory?
A. Yes, except that it is derived from Large(L) and small(s) intervals instead of Wholetones and semitones of 12tET. It is a diatonic, negative meantone temperament. LucyTuning can map any combination and permutation of Large and small intervals that you can imagine for all Western scales and all known “ethnic” scales, plus an infinity of new possibilities.
