Pythagorean Comma




This interval has serious implications for the various Tuning schemes of the Chromatic Scale , because in Western music, 12 Perfect Fifths and seven octaves are treated as the same interval. Equal Temperament , today the most common tuning system used in the West, gets around this problem by flattening each fifth by a twelfth of a Pythagorean comma (2 cents), thus giving perfect octaves.

Another interval of similar size is the Syntonic Comma .
