The cataharry family of rank three temperaments tempers out the cataharry comma, 19683/19600.


Comma: 19683/19600
The '''cataharry family''' of [[rank-3 temperament]]s [[tempering out|tempers out]] the [[cataharry comma]] ({{monzo|legend=1| -4 9 -2 -2 }}, [[ratio]]: 19683/19600).


7 and 9 limit minimax
== Cataharry ==
Cataharry splits the [[3/1|3rd harmonic]] into two semitwelfths. Bending the semitwelfth up by a [[syntonic comma]] results in ~[[7/4]], and down results in ~[[12/7]].

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).
