Varunismic temperaments

This is a list showing technical temperament data. For an explanation of what information is shown here, you may look at the technical data guide for regular temperaments.

This is a collection of rank-2 varunismic temperaments, which temper out the varunisma (monzo: [-9 8 -4 2⟩, ratio: 321489/320000). For the rank-3 temperament tempering out 321489/320000 in the 7-limit, see Miscellaneous 7-limit temperaments #Varuna.

Temperaments discussed elsewhere are:

• Injera (+50/49 or 81/80) → Meantone family
• Diaschismic (+126/125) → Diaschismic family
• Bischismic (+3136/3125) → Schismatic family
• Unidec (+1029/1024) → Gamelismic clan
• Bamity (+245/243) → Amity family
• Fifives (+875/864) → Fifive family
• Bicommatic (+10976/10935) → Hemimage temperaments
• Decile (+235298/234375) → Quintile family
• Compton (+225/224) → Compton family
• Harry (+2401/2400) → Gravity family
• Bison (+6144/6125) → Sensipent family
• Narayana (+65625/65536) → Vishnu family

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.
