In music, the schisma (also spelled skhisma) is the interval between the syntonic comma (81:80) and the Pythagorean comma which is slightly larger. It equals or ≈ 1.00113, which corresponds to 1.9537 cents (). It may also be defined as: the difference (in cents) between 8 justly tuned perfect fifths plus a justly tuned major third and 5 octaves; the ratio of major limma to the Pythagorean limma; the ratio of the syntonic comma and the diaschisma.
