Revision as of 13:45, 13 April 2025 by FloraC (talk | contribs) (Text replacement - "{{Technical data page}}<br><br>" to "{{Technical data page}}")
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.

The shibboleth family tempers out the shibboleth comma, 1953125/1889568.

Temperaments discussed elsewhere include:

Shibboleth

Subgroup: 2.3.5

Comma list: 1953125/1889568

Mapping[1 4 5], 0 -9 -10]]

Optimal tunings:

  • CTE: ~2 = 1\1, ~6/5 = 321.773
  • POTE: ~2 = 1\1, ~6/5 = 321.852

Optimal ET sequence15, 26, 41, 179c, 220c, 261cc, 302cc

Badness: 0.227553

Superkleismic

The S-expression-based comma list of superkleismic is {S5/S6, S7/S8, S10, S12(, S21)}. Through careful observation of the equivalences therein one can derive that a sharpened ~6/5 is the generator as well as the mapping of the full 13-limit.

Subgroup: 2.3.5.7
