Interval information |
reduced
2601/2600 is a 17-limit (also 2.3.5.13.17 subgroup) superparticular comma measuring about 0.67 cents. It may be properly described as the septendecimal sixth-tones comma, since it is the difference between 51/50 and 52/51, the two 17-limit sixth-tones. Another prominent identity is the little gap between 18/13 and a stack of two 20/17's.
In terms of commas, it is the difference between 289/288 and 325/324, between 833/832 and 1225/1224, between 1156/1155 and 2080/2079, between 1275/1274 and 2500/2499, between 1701/1700 and 4914/4913, and between 2401/2400 and 31213/31212.
Temperaments
Tempering out this comma results in 26/25 being split into two equal parts, each representing 51/50~52/51, and enables the related essentially tempered chords.
