# Minortonic family

The **minortonic family** tempers out the minortone comma (also known as "minortonma"), [-16 35 -17⟩. The head of this family is five-limit minortone temperament, with generator a minor tone.

## Minortone

Subgroup: 2.3.5

Comma: [-16 35 -17⟩

Mapping: [⟨1 -1 -3], ⟨0 17 35]]

POTE generator: ~10/9 = 182.466

Optimal GPV sequence: 46, 125, 171, 388, 559, 730, 1289, 2019, 2749, 4768, 16323, 21091

Badness: 0.029765

## Mitonic

As a 5-limit temperament, mitonic becomes minortonic, a super-accurate microtemperament tempering out the minortone comma, [-16 35 -17⟩. Flipping that gives the 5-limit wedgie ⟨⟨17 35 16]], which tells us that 10/9 can be taken as the generator, with 17 of them giving a 6, 18 of them a 20/3, and 35 of them giving a 40. The generator should be tuned about 1/16 of a cent flat, with 6^{1/17} being 0.06423 cents flat and 40^{1/35} being 0.06234 cents flat. 171, 559 and 730 are possible equal temperament tunings.

However, as noted before, 32/21 is only a ragisma shy of (10/9)^{4}, and so a 7-limit interpretation, if not quite so super-accurate, is more or less inevitable. While 559 or 730 are still fine as tunings, the error of the 7-limit is lower by a whisker in 171edo. 21 generators gives a 64/7. MOS of size 20, 33, 46 or 79 notes can be used for mitonic.

### Mineral

Extending mitonic to the 11-limit is not so simple. There are two mappings that are comparable in complexity and error: *mineral* (46&171) and *ore* (46&125). The mineral temperament tempers out 441/440 and 16384/16335 in the 11-limit. In the 17-limit, both mineral and ore temper out 833/832, 1225/1224, 1701/1700, and 4096/4095 (2.3.5.7.13.17 commas). The word "mineral" is related to "mine" (an excavation from which ore or solid minerals are taken) and "miner" (a person who works in a mine, also as a pun on "minor").

### Ore

## Domain

Domain temperament adds the landscape comma, 250047/250000, to the minortone comma, giving a temperament which is perhaps most notable for its inclusion of the remarkable subgroup temperament terrain.
