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.

This is a collection of rank-2 cataharry temperaments, which temper out the cataharry comma (monzo[-4 9 -2 -2, ratio: 19683/19600). For the family of rank-3 temperaments, see Cataharry family.

Discussed elsewhere are:

Considered below is swetneus and majvamoid, in the order of increasing badness.

Swetneus

The swetneus temperament takes its name from the fact that an approximate swetismic neutral second, ~49/45, is the generator.
