Varunismic temperaments
This is a collection of rank-2 temperaments tempering out the varunisma, 321489/320000 = [-9 8 -4 2⟩.
Temperaments discussed elsewhere are:
- Injera (+50/49 or 81/80) → Meantone family
- Diaschismic (+126/125) → Diaschismic family
- Compton (+225/224) → Compton family
- Bamity (+245/243) → Amity family
- Unidec (+1029/1024) → Gamelismic clan
- Harry (+2401/2400) → Gravity family and Breedsmic temperaments
- Bischismic (+3136/3125) → Schismatic family
- Bison (+6144/6125) → Sensipent family
- Commatic (+10976/10935) → Hemimage temperaments
- Narayana (+65625/65536) → Vishnuzmic family
- Decal (+235298/234375) → Pental family
- Bosonic (+589824/588245) → 26th-octave temperaments
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.
