Temperaments

Tempering out this comma results in the 7-limit version of the mirwomo temperament. Mirwomo has a canonical 11-limit extension that tempers out 243/242 and 385/384, as 33075/32768 = (243/242)⋅(385/384)² (→ Rastmic rank-3 clan #Mirwomo).

Mirwomo is tempered out in rank-2 temperaments such as miracle, worschmidt, and mohajira. See Mirwomo temperaments for a collection of rank-2 temperaments in which the comma gets tempered out.

Etymology

As is noted above, the mirwomo comma is tempered out in miracle, worschmidt, and mohajira, and so the name is probably a contraction of these three names.
