meantone

Etymology

From mean + tone.

meantone means A musical temperament that generates all non-octave intervals from a stack of identical perfect fifths all tuned flat from their just ratio of 3/2. When the amount of flattening makes the major and minor thirds appropriate sizes, the syntonic comma is tempered out to a unison. Lexicurio rates it Sui generis — a strength score of 96 out of 100.
