10th-octave temperaments

Revision as of 20:07, 1 August 2026 by Eliora (talk | contribs) (Neon: see also here is a tautology, a simple in-text link calling it neon comma suffices.)
This is a list showing technical temperament data. For an explanation of what information is shown here, you may look at the technical data guide for regular temperaments.

10edo is notable for having close approximations of 15/14 to one step, the associated comma being the linus comma and 13/8 to 7 steps. 10th-octave temperaments naturally occur between any equal divisions of the octave whose greatest common divisor is 10.

Temperaments discussed elsewhere include: decoid, decile, decimetra, decistearn, decavish, and linus (the 15/14 relationship mentioned above).

Valerismic (rank-1)

Valerismic temperament tempers out the valerisma, 137858491849/137438953472.

Subgroup: 2.13

Comma list: 2.13 [-37 10

Subgroup-val mapping[10 37]]

mapping generators: ~2197/2048 = 1\10

Supporting ETs: 10N, N = 1 to 113

Neon

For extensions, see Ragismic microtemperaments #Deca, Landscape microtemperaments #Zinc, and 20th-octave temperaments #Calcium.

Neon tempers out the neon comma, [21 60 -50 in the 5-limit, equating 3125/2916 with one step of 10edo. It was named by Eliora in 2023 after the 10th element.

Extending neon with ragisma, or equivalently with the linus comma, produces deca.

Subgroup: 2.3.5
