Inu comma
81/76, Boethius' chromatic semitone, is a 19-limit interval of about 110.3 cents in size. It differs from 2187/2048, the Pythagorean apotome, by 513/512, the undevicesimal schisma or Boethius' comma, hence the name. It also differs from 16/15 by 1216/1215, and is the difference between 19/16 (otonal minor third) and 81/64 (Pythagorean major third) and thus is 81/80 larger than 20/19.
Temperaments
This interval has been proposed to be used as a comma to be tempered out, though the musical utility of it is unknown yet. The name dog comma was suggested by Xenllium in 2023, translated from Japanese word 犬 (いぬ, inu), a play of its color name, inu (as the identical pronunciation).
