pub const COMMON_EQUAL_TEMPERAMENTS: [TuningSystem; 8];Expand description
The equal divisions of the octave that xenharmonic practice actually uses.
Any equal division is already expressible as a TuningSystem::Equal;
this names the ones worth reaching for. 19 and 31 support meantone, 22 deliberately does not,
53 gets 5-limit harmony almost exact, and 72 is the usual choice for
notating 11-limit music.
