Pluto, named by [[Gene Ward Smith]] in 2010<ref>[https://yahootuninggroupsultimatebackup.github.io/tuning-math/topicId_18465.html Yahoo! Tuning Group | ''19-limit Pluto temperament'']</ref>, can be described as the {{nowrap| 41 & 80 }} temperament. It is generated by a flattened [[~]][[10/7]] [[tritone]], seven of which give the [[interval class]] of [[3/1|3]], and the [[ploidacot]] for this temperament is gamma-heptacot. [[121edo|59\121]] is about perfect as a tuning.

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 temperaments tempering out the octagar comma (monzo[5 -4 3 -2, ratio: 4000/3969).

Temperaments discussed elsewhere are:

Considered below are pluto, slithy, tridecatonic, slendi and dhaivatic, in the order of increasing badness.

Pluto

Not to be confused with Plutus.

Pluto, named by Gene Ward Smith in 2010[1], can be described as the 41 & 80 temperament. It is generated by a flattened ~10/7 tritone, seven of which give the interval class of 3, and the ploidacot for this temperament is gamma-heptacot. 59\121 is about perfect as a tuning.

Slendi

Slendi may be described as the 41 & 42 temperament. It has a generator of 49/48, seventeen of which give 4/3. Its ploidacot is omega-17-cot.

The name was likely derived from slendro diesis, one of the names for the interval 49/48.
