81/76, the dog comma is a 19-limit interval, 110.3 cents in size. It is the difference between 19/16 (otonal minor third) and 81/64 (Pythagorean major third) and thus is 81/80 larger than 20/19.

Etymology

The word dog for this interval was introduced by Xenllium in 2023. It was translated from Japanese word 犬 (いぬ, inu), a play of its color name, inu (as the identical pronunciation).

Temperaments

Tempering this interval leads to a 2.3.19 version of mavila where four mavila fifths yields 19/16, so is potentially of relevance in 16edo if one wants to interpret its fifth as a 27 ¢ flat ~3/2.
