Comma (or coma) -- A minute interval or difference in the pitches of the same musical tone occasioned by different systems of tuning. The comma of Didymus is an interval such as that between two enharmonically equivalent notes like B-sharp and C-natural, an amount of 24 cents. (cents are 1/100th of a semitone) The syntonic comma is the interval between a just major third (5:4) and a Pythagorean third (81:84). The comma of Pythagoras (known also as the ditonic comma) is the difference between a cycle of just fifths and seven perfect octaves. In equal temperament tuning this comma is absorbed by the diminishing of each successive fifth in the cycle by the amount of 1/12th of the comma.
