# Vishnuzmic family

(Redirected from Acyuta)

The vishnuzmic family of temperaments tempers out the vishnuzma, [23 6 -14 = 6115295232/6103515625, a 5-limit comma of about 3 cents. It is the amount by which seven just chromatic semitones of 25/24 fall short of a just perfect fourth of 4/3, or in other words (4/3)/(25/24)7.
