Enharmonic Genus
In ancient Greek music the enharmonic was 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

Famous quotes containing the word genus:
“Methinks it would be some advantage to philosophy if men were named merely in the gross, as they are known. It would be necessary only to know the genus and perhaps the race or variety, to know the individual. We are not prepared to believe that every private soldier in a Roman army had a name of his own,—because we have not supposed that he had a character of his own.”
—Henry David Thoreau (1817–1862)
