Temperament pages

Reverting all the databoxes, but the cleanup will continue

Note:

1. Order: subgroup, comma list, mapping, mapping generators, gencom mapping, gencom, map to lattice, lattice basis, wedgie, minimax tuning, tuning ranges, algebraic generator, vals, badness, complexity spectrum.
2. Comma list shows 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. Minimax tuning are based on tonality diamond, so it should explicitly state the odd limit, or a diamond function of ratios.
5. Use 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".

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.
