A perfect fifth in meantone, and in common practice theory, consists of four diatonic semitones and three chromatic semitones. In [[12edo|12edo]], and hence in most discussions these days, that is simplified to seven semitones. On the other hand, in just intonation it consists of four just diatonic semitones of 16/15, three just chromatic semitones of 25/24, and two Didymus commas of 81/80, and is the [[just_perfect_fifth|just perfect fifth]] of 3/2.
