'''Mabilic''' is a [[regular temperament|temperament]] in the [[2.5.7 subgroup|2.5.7]] [[subgroup]] where [[5/2]] is split into three [[generator]]s, five of which octave-reduced reach [[8/7]]. The generator is a sharpened fourth (or, conversely, a flattened fifth) in size, best tuned around 528 [[cent]]s. Mabilic, as a result, tempers out the [[mabilisma]] 1071875/1048576. Mabilic is arrived at by removing the inaccurate 3/2 mapping from [[armodue (temperament)|armodue]] temperament. As such, mabilic can be associated with [[mos scale]]s like [[antidiatonic]] and [[armotonic]]. Thus, while the generating interval is not [[3/2]], [[2L 5s #Notation|melodic]] [[chain-of-fifths notation]] makes some amount of sense to use here. | |||
Mabilic can be extended into a full 7-limit temperament called '''trismegistus''' in which 3 is found at 15 steps. Since 5 is at 3 steps, that makes trismegistus a magic temperament. Similarly, since 8/7 is at 5 steps, trismegistus is a slendric temperament.Trismegistus is associated with the | Mabilic can be extended into a full [[7-limit]] temperament called '''trismegistus''' in which [[3/1|3]] is found at 15 steps. Since [[5/1|5]] is at 3 steps, that makes trismegistus a [[magic family|magic temperament]]. Similarly, since 8/7 is at 5 steps, trismegistus is a [[gamelismic clan|slendric temperament]]. Trismegistus is associated with the mos scale [[9L 7s]], where 3/2 is found as the "augmented" version of the generator, and [[25edo]], [[41edo]], and [[66edo]] make for good tunings. | ||
There is an alternative extension, '''semabila''' ([[Mabila family#Semabila]]), which is a semaphore temperament (hence its name) and thus finds 4/3 at 10 generators. It is best tuned sharper than trismegistus. | There is an alternative extension, '''semabila''' ([[Mabila family #Semabila]]), which is a [[semaphoresmic clan|semaphore temperament]] (hence its name) and thus finds [[4/3]] at 10 generators.
