Keenanismic temperaments

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) → 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. The extension to the 2.3.5.7.11.13.17 subgroup tempers out 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. The S-expression-based comma list of this extension is {(S17,) S33, S34, S35 = S49*S50(, S99 = S33/S35)}.

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.
