Revision as of 09:28, 12 September 2023
This is a collection of rank-3 temperaments tempering out the keenanisma, 385/384. For the rank-4 keenanismic temperament, see Keenanismic family.
Temperaments discussed elsewhere include:
- Selenium (+49/48 or 56/55) → Semiphore family
- Polyhymnia (+81/80 or 385/384) → Didymus rank-3 family
- Orwellian (+99/98) → Orwellismic family
- Supermagic (+100/99) → Keemic family
- Zeus (+121/120 or 176/175) → Porwell family and Biyatismic clan
- Starling (+126/125) → Starling family
- Marvel (+225/224) → Marvel family
- Mirwomo (+243/242) → Rastmic rank-3 clan
- Sensamagic (+245/243) → Sensamagic family
- Portent (+441/440) → Gamelismic family
- Augustus (+1232/1215) → Diaschismic rank-3 family
- Agni (+1375/1372) → Breed family
- Beyla (+4375/4374) → Ragismic family
- Enlil (+6250/6237) → Kleismic rank-3 family
Considered below are uniwiz and tritiwiz.
Uniwiz
Uniwiz tempers out 1500625/1492992 = [-11 -6 4 4⟩ in the 7-limit, and the keenanisma, 385/384, the kalisma, 9801/9800, as well as the Alpharabian comma, 131769/131072 = [-17 2 0 0 4⟩, in the 11-limit. In the 17-limit it tempers two no-13's 17-limit PIFE commas, 561/560 and 595/594, along with their product, 289/288, thus also equating the half-octave with 17/12~24/17.
It features the split of the whole tone into four equal parts, each representing 36/35~35/34~34/33~33/32. Therefore, it is most interesting to those who would like to make extensive use of quartertones. It can be viewed as the temperament described by the three quartertone-size equal temperaments: 22, 24 and 26. In the 11-limit it shares the optimal patent val, 284, with keenanismic.
