Naquian music

Naquian music uses 7-tone scales rich in neutral thirds. Scales are abstractly viewed as subsets of 27 roughly equal divisions of the octave. The 3L 4s MOS scale (5 3 3 5 3 5 3) may be used, but they use other, non-MOS 7-note scales too. The quasi-equal 6L 1s MOS scale (4 4 4 4 4 4 3) in 27edo is mainly used as a reference point rather than actual music, in that notation is based on the 6L 1s scale in the same way that Western notation is based on the diatonic scale.

Movement by one step of 27edo is usually avoided, since it is difficult to sing.

Historically other micro-divisions have been used or proposed - especially 27-well temperaments, 17-well temperaments or 17-equal.

Sjowaazhosphere music

Tuning-wise, Sjowaazheñ music is based on the meantone diatonic scale like Western music, but uses modal rather than tonal harmony; modes other than major and minor are common.
