- Limma
The word limma or leimma can refer to several different musical intervals, whose only common property is their small size:
*The original Pythagorean limma, 256/243, discussed at
Pythagorean interval (Audio|Pythagorean minor semitone on C.mid|play).*The 5-limit limma, 128/125, the amount by which three just
major third s fall short of an octave (Audio|5-limit limma on C.mid|play).*The
major limma , 135/128, which is the difference between two major whole tones and aminor third (Audio|Greater chromatic semitone on C.mid|play).*The 5-limit diatonic semitone, 16/15 (Audio|Just diatonic semitone on C.mid|play). Although closer in size to the Pythagorean apotome than to the limma, it has been so called because of its function as a diatonic semitone rather than a chromatic one.
