Trimyna can be described as the {{nowrap| 27e & 29 & 31 }} temperament. All three equal temperaments have a fairly accurate tritone for ~10/7, and trimyna takes it as one of its generators, five of which get us to the [[6/1|6th]] [[harmonic]]. The name ''trimyna'' is a contraction of ''[[tritonic]]'' and ''[[myna]]''.

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-3 temperaments tempering out the werckisma (ratio: 441/440, monzo: [-3 2 -1 2 -1⟩). For the rank-4 werckismic temperament, see Catalog of rank-4 temperaments #Werckismic (441/440).

Temperaments discussed elsewhere are:

Considered below are history, varuna, and trimyna.

History

For the 7-limit version, see Miscellaneous 7-limit temperaments #History.

History, named by Graham Breed some time before 2011[1], splits the perfect fourth into six, each for 21/20~22/21. A recommendable tuning is given by 289edo.

Trimyna

For the 7-limit version, see Miscellaneous 7-limit temperaments #Trimyna.

Trimyna can be described as the 27e & 29 & 31 temperament. All three equal temperaments have a fairly accurate tritone for ~10/7, and trimyna takes it as one of its generators, five of which get us to the 6th harmonic. The name trimyna is a contraction of tritonic and myna.
