~~In [[aberrismic theory]],~~ '''~~sequar5m~~''' (in aberrismic systematic naming) is the [[~~diregular scale|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''' (in [[aberrismic theory|aberrismic]] systematic naming) is the [[even-regular]] 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.

~~Sequar5m hence~~ admits a [[Cata]] ~~temperament interpretation~~.

Here L = ~13/12, m = ~26/25~27/26, and s = ~40/39.

(Hence Cthon5m admits an Island (2.3.5.13[ [[676/675]] ] temperament) interpretation.)

As a 2.3.5.13 subgroup scale, 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 cthon5m has 10 3/2's.

* 3/2 chains in Kleismic[15] only have at most 3 notes whereas cthon5m interpreted in Kleismic has 3/2 chains with 3 and 4 notes.

==== Kleismic ====

Kleismic (properly [[Cata]]) tempering corresponds to using Island tempering and then letting L = 2m. This makes Kleismic-tempered cthon5m a subset of a permutation (mmmmmsmmmsmmmmsmmms) of the Kleismic[19] MOS.
