The name ''quindromeda'' comes from "quintans" (Latin for "one fifth") and "[[Wikipedia:Andromeda|Andromeda]]", because the generator is 1/5 of the [[Schismatic family #Garibaldi|andromeda]] fourth (~4/3, about 497.6 cents). | |||

The quindromeda temperament works well for the 2.3.5.17.19 subgroup, tempering out the password comma ([[1216/1215]]), aureusma ([[1445/1444]]), and 6144/6137. An obvious 17-limit interpretation of the generator is ~[[18/17]], equating three 18/17s with [[19/16]], five 18/17s with [[4/3]], and twenty-eight 18/17s with the [[5/1|fifth harmonic]]. | |||

The ''quintagar'' temperament (12&217) tempers out the hemimean comma (3136/3125) and the [[garischisma]] (33554432/33480783) in the 7-limit.
