Temperament pages

Databoxes has been canceled, but the cleanup will continue

Note:

  1. Order: subgroup, comma list, (sval) mapping, (sval) mapping generators, gencom mapping, gencom, map to lattice, lattice basis, wedgie, POTE generator(s), minimax tuning, tuning ranges, algebraic generator, vals, badness, complexity spectrum, and others.
  2. Comma list should show the simplest commas sufficient to define the temperament, stated in Normal lists #Normal interval list.
  3. Mapping generators should show all the ratios as used in the mapping, including the period.
  4. Since minimax tuning are based on tonality diamond, it should explicitly state the odd limit, or a diamond function of ratios.
  5. Replace "EDOs" with Template:Val list.
  6. For subgroup temperaments, "mapping" becomes "sval mapping", add "gencom mapping" and "gencom". If TE is TE is TE (sic), simply show "POTE", otherwise show "POL2" or "POT2" instead of "POTE".

Get a family for:

  • Ripple (3 different 7-limit extensions) done
  • Smate (2 different 7-limit extensions) done
  • Parakleismic (2 different 7-limit extensions) canceled, not strong extensions
  • Superpyth (2 different 7-limit extensions) canceled, not strong extensions

Septimal meantone

Deutsch

Main article: Meantone
See also: Wikipedia: Septimal meantone temperament

The 7/4 of septimal meantone is the augmented sixth, C-A#, and other septimal intervals are 7/6, C-D#, the augmented second, 7/5, C-F#, the tritone, and 21/16, C-E#, the augmented third. Septimal meantone tempers out the common 7-limit commas 126/125 and 225/224 and in fact can be defined as the 7-limit temperament that tempers out any two of 81/80, 126/125 and 225/224.
