This page collects nuwell temperaments, which temper out the nuwell comma (monzo: [1 5 1 -4⟩, ratio: 2430/2401). Its fundamental equivalence entails that 7/6 is sharpened so that it stacks four times to reach 15/8. Most of these temperaments extend to the 11-limit by equating 11/8~15/11 with (7/6)2, tempering out 99/98 and 121/120.

For the rank-3 temperament, see Miscellaneous 7-limit temperaments #Nuwell.

Maja

For the 5-limit version, see Schismic–Mercator equivalence continuum #Maja (5-limit).

Maja tempers out 3125/3087, the gariboh comma, and 4375/4374, the ragisma, in addition to the nuwell comma, and may be described as the 8d & 53 temperament. It was named by Petr Pařízek in 2011 for ~13/10 is a generator for the 13-limit version and that M and J are the 13th letter and the 10th letter, respectively[1]. It is unrelated to either the major quality or magic temperament. Note that in the data below, the generator is its octave complement, such that seventeen of them octave reduced reach the perfect fifth. Its ploidacot is iota-17-cot.
