Enharmonic

An enharmonic is one of the three Greek genera in music, in which the tetrachords are divided (descending) as a ditone plus two microtones. The ditone can be anywhere from 16/13 to 9/7 (3.55 to 4.35 semitones) and the microtones can be anything smaller than 1 semitone. Some examples of enharmonic genera are 1. 1/1 36/35 16/15 4/3 2. 1/1 28/27 16/15 4/3 3. 1/1 64/63 28/27 4/3 4. 1/1 49/48 28/27 4/3 5. 1/1 25/24 13/12 4/3
