Limma
From Wikipedia, the free encyclopedia
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 intervals.
- The 5-limit limma, 128/125, the amount by which three just major thirds fall short of an octave.
- The 5-limit diatonic semitone, 16/15. 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.
