The '''quartisma''' is the ratio 117440512/117406179 (in [[monzo]] form, {{monzo|24 -6 0 1 -5}}), or the difference between six [[33/32]] quarter tones and one [[77/64]] minor third.

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 rank-3 '''quartismic temperament''' is the rank-3 2.3.7.11 temperament that tempers out this comma; equivalently it is the 22&24&159 temperament. The page will also list various rank-2 temperaments that temper out this comma and thus belong in the quartismic family.

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]].
