Mabilic and trismegistus
| Mabilic; trismegistus |
1029/1024, 3125/3072 (2.3.5.7)
Mabilic is a temperament in the 2.5.7 subgroup where 5/2 is split into three generators, 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 cents. Mabilic, as a result, tempers out the mabilisma 1071875/1048576. Mabilic is arrived at by removing the inaccurate 3/2 mapping from armodue temperament. As such, mabilic can be associated with MOS scales like antidiatonic and armotonic. Thus, while the generating interval is not 3/2, 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 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.
Making the generator itself 4/3 leads to the exotemperament mavila, after which mabilic is named.
The tuning optimum of mabilic is 527.2 cents, which is almost exactly the golden antidiatonic generator.
