Cthon5m (in aberrismic systematic naming) is the diregular 5L5m4s scale pattern LmLsmLsmLmsLms, so named because it is generated by a generator of the semiquartal MOS and the m step is the offset in its generator-offset structure.
Cthon5m is comprised of two interleaved nicetone/Zarlino scales of opposite chirality. In the JI preimage below these are 5-limit Zarlino scales.
Temperaments
Cata (2.3.5.13[34&53])
Cthon5m has the following 2.3.5.13 interpretation in the 34edo (4:2:1) and 53edo (6:3:2) tunings:
13/12 9/8 39/32 5/4 13/10 45/32 13/9 3/2 13/8 27/16 26/15 15/8 39/20 2/1
(Cthon5m hence admits a Cata temperament interpretation.)
Cthon5m is comparable to the MOS Kleismic[15] in size, but it's "fifthier" than Kleismic[15] and has one fewer note:
- Kleismic[15] has 9 3/2's whereas cthon4s has 10 3/2's.
- 3/2 chains in Kleismic[15] only have at most 3 notes whereas cthon4s interpreted in Kleismic has 3/2 chains with 3 and 4 notes.
