The '''quartismic family''' is built up from temperaments that temper out the [[quartisma]]- the unnoticeable comma with the ratio 117440512/117406179, and a monzo of {{monzo|24 -6 0 1 -5}}. Among the members of this family are Altierran, Meanquarter, Coin, Kleirtismic, and Doublefour.

The '''quartismic family''' is a family of [[rank-4]] temperaments tempers out the [[quartisma]] the unnoticeable comma with the ratio 117440512/117406179, and a monzo of {{monzo|24 -6 0 1 -5}}, however, most of the members of this rank-4 family currently have yet to be explored. For other families that are defined by the tempering of this comma, see [[the Quartercache]].

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 [[Microtempering|microtemperament]].


Comma: 117440512/117406179
The 11-limit parent comma for the quartismic family is the the quartisma with a ratio of 117440512/117406179 and a monzo of {{monzo| 24 -6 0 1 -5 }}. As the quartisma is an unnoticeable comma, this rank-4 temperament is a [[microtemperament]].

There are some temperaments in the quartismic family in which only the quartisma is tempered out, but without any regard to the five-limit.

== 5-limit Representation ==
Among quartismic temperaments, there are several options for 5-limit representation depending which among the various 5-limit commas is tempered out.  Adding the [[schisma]] to the list of tempered-out commas results in some form of Altierran temperament.  Adding the [[81/80|meantone comma]] results in some form of Meanquarter temperament.  Adding the [[Magic_comma|magic comma]] results in some form of Coin temperament.  Adding the [[15625/15552|kleisma]] results in some form of Kleirtismic temperament- the "kleir-" in "Kleirtismic" is pronounced the same as "Clair".  Adding the [[Tetracot_comma|tetracot comma]] results in some form of Doublefour temperament.  Other possible extensions are listed here.
 
===Shrutar extension===
This is the 22&46 temperament.  See [[Diaschismic_family#Shrutar|Shrutar]].
===Escapade extension===
This is the 22&43 temperament.  See [[Escapade_family|Escapade]].
 
= Altierran =
The Altierran clan is the temperament clan consisting of those temperaments in which both the schisma and the quartisma are tempered out.
