FloraC: The temp's name is vishnu, so vishnu comma is arguably standard

2026-06-18T06:34:15Z

The temp's name is *vishnu*, so *vishnu comma* is arguably standard

	The '''vishnuzma''' or '''semisuper comma''' ([[ratio]]: ~~6115295232~~/~~6103515625~~, [[monzo]]: {{monzo\| 23 6 -14 }}) of 3.~~338~~ [[cent]]s, is the amount by which seven [[25/24\|classical chromatic semitones]] ~~fall~~ short of a ~~just perfect fourth and also by which fourteen~~ [[5/4~~\|classical major thirds]] miss the [[729~~/~~512~~\|~~pythagorean augmented~~ fourth]]; in other words the interval (4/3)/(25/24)<sup>7</sup>.		The '''vishnu comma''', '''vishnuzma''' or '''semisuper comma''' ([[ratio]]: 6 115 295 232 / 6 103 515 625, [[monzo]]: {{monzo\| 23 6 -14 }}), is an [[unnoticeable comma\|unnoticeable]] [[5-limit]] [[comma]] measuring about 3.34 [[cent]]s. It is the amount by which a stack of seven [[25/24\|classical chromatic semitones]] falls short of a [[4/3\|just perfect fourth]], in other words the interval (4/3)/(25/24)<sup>7</sup>. Equivalently, it is the amount by which a stack of fourteen [[5/4\|classical major thirds]] misses the [[729/512\|Pythagorean augmented fourth]].
