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


== Swetneus ==
== Swetneus ==
The swetneus temperament takes its name from the fact that an approximate swetismic neutral second, ~49/45, is the generator.
Swetneus tempers out the [[trimyna comma]] and may be described as the {{nowrap| 58 & 91 }} temperament. It takes its name from the fact that the generator is [[~]][[49/45]], a [[neutral second]] that is a [[swetisma]] away from [[12/11]]. Note that in the data that follow, the generator is its [[octave complement]], ~[[90/49]], so that twenty of them reach the [[interval class]] of [[3/1|3]]. In the [[11-limit]], this generator is equated with not [[11/6]] but [[81/44]].

The ''majvamoid'' temperament (149&183) is an extension of the [[Subgroup temperaments #No-sevens subgroup|majvam]] temperament which tempers out the cataharry comma and the quasiorwellisma (29360128/29296875, sazoquinbigu) in the 7-limit.
Named by [[Xenllium]] in 2021, majvamoid tempers out the [[quasiorwellisma]] and may be described as the {{nowrap| 149 & 183 }} temperament. It is an [[extension]] of the [[majvam]] temperament.

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

Swetneus tempers out the trimyna comma and may be described as the 58 & 91 temperament. It takes its name from the fact that the generator is ~49/45, a neutral second that is a swetisma away from 12/11. Note that in the data that follow, the generator is its octave complement, ~90/49, so that twenty of them reach the interval class of 3. In the 11-limit, this generator is equated with not 11/6 but 81/44.
