This is a collection of rank-2 temperaments tempering out the varunisma, 321489/320000 = [-9 8 -4 2.

Temperaments discussed elsewhere are:

Essence

Essence is of interest because of the abundant supply of essentially tempered chords. Specifically, werckismic chords, squbemic chords, cuthbert chords, sinbadmic chords, and petrmic chords in the 13-odd-limit, in addition to nicolic chords in the 15-odd-limit.
