Semicanousmic clan
The semicanousmic clan of rank-3 temperaments tempers out the semicanousma, 14641/14580 = [-2 -6 -1 0 4⟩.
Temperaments discussed elsewhere are:
- Urania (+81/80 or 121/120) → Didymus rank-3 family
- Triglav (+3025/3024 or 3136/3125) → Hemimean family
- Semicanou (+9801/9800) → Canou family
Considered below are syndeute and hemireiwa, in addition to deuteromere, the no-7 subgroup temperament.
For the rank-4 semicanousmic temperament, see Rank-4 temperament #Semicanousmic (14641/14580).
