The quartisma is significant on account of it being the difference between a stack of five [[33/32]] quartertones and one [[7/6]] subminor third in Just Intonation. Tempering it out leads to '''quartismic temperament''' or '''Saquinlu-azo temperament'''. For a list of such temperaments, see [[Quartismic family]].
