Superkleismic

Superkleismic is a regular temperament defined in the 7-, 11-, and 13-limit. It is a member of shibboleth family as well as of the gamelismic clan. The minor-third generator of superkleismic is ~6.3 cents sharp of 6/5, even wider than the kleismic minor third (~317 cents), and from this it derives its name. The two mappings unite at 15edo. While not as simple or accurate as kleismic in the 5-limit, it comes into its own as a 7- and 11-limit temperament, approximating both simply and accurately in good tunings. Discarding the harmonics 3 and 5 and concentrating purely on that subgroup gets you orgone. 41edo is a good tuning for superkleismic, with a minor-third generator of 11\41, and mosses of 11, 15, or 26 notes are available.

See Shibboleth family #Superkleismic for more technical data.
