This is a list showing technical temperament data. For an explanation of what information is shown here, you may look at the technical data guide for regular temperaments.

The cataharry family of rank-3 temperaments tempers out the cataharry comma (monzo: [-4 9 -2 -2⟩, ratio: 19683/19600).

Cataharry

Cataharry splits the 3rd harmonic into two semitwelfths. Bending the semitwelfth up by a syntonic comma results in ~7/4, and down results in ~12/7.
