These are very low complexity temperaments tempering out the septimal minor semitone, 21/20, and hence equating 5/3 with 7/4, and 10/7 with 3/2.
Temperaments discussed elsewhere are:
- Mother (+16/15) → Father family
- Sharptone (+28/27) → Meantone family
- Pelogic (+135/128) → Pelogic family
- Flat (+25/24) → Dicot family
- Beep (+27/25) → Bug family
- Deflated (+21/20) → Augmented family
- Gidorah (+144/125) → Gamelismic clan
- Oxygen (+175/162) → Porcupine family
Considered below are fluorine and sodium.
