Quartismic family
|
Todo: discuss title This doesn't follow the definition of temperament family |
The quartismic family is built up from temperaments of various ranks that temper out the quartisma- the unnoticeable comma with the ratio 117440512/117406179, and a monzo of [24 -6 0 1 -5⟩. Among the members of this family are quartismatic, altierran, meanquarter, coin, escapismic, dietismic, kleirtismic, and doublefour.
Quartismic
The 11-limit parent comma for the quartismic family is the the quartisma with a ratio of 117440512/117406179 and a monzo of [24 -6 0 1 -5⟩. As the quartisma is an unnoticeable comma, this rank-4 temperament is a microtemperament.

Quartismatic
There are some temperaments in the quartismic family in which the quartisma is tempered out, but without any sort of five-limit representation. This particular temperament is the parent temperament of all such no-fives children, and is referred to as Saquinlu-azo temperament in color notation.

Escapismic
In escapisimic, both the escapade comma and the quartisma are tempered out, thus, it is essentially an escapade expansion.

Dietismic
In dietismic, both the diaschisma and the quartisma are tempered out. Dietismic can easily be further tempered to shrutar, and in fact, it is rather unusual to find a different tempering option.
