Temperaments that fall outside of the "historically considered meantone" | === Preservation of meantone behavior === | ||
Temperaments that fall outside of the "[[Historical temperaments|historically considered meantone]]" range will not possess most of the properties that meantone usually possesses, but they are included for completeness. | |||
== | Temperaments that fall outside of the "[[diamond monotone]]" range preserve even fewer meantone properties, but they are also included for completeness. | ||
=== Extra inclusions === | |||
A small number of additional temperaments are included. Not too many, to avoid clutter, just the bare minimum: | A small number of additional temperaments are included. Not too many, to avoid clutter, just the bare minimum: | ||

=== Characteristics included === | |||
Some of the characteristics this table mentions for each temperament include: | |||
* Whether it saw historical (pre-1950) use | |||
* Whether it is close to (i.e. within 1/2 a degree of closing of) an edo smaller than 100 | |||
* Whether it is the closest on the table to an optimised tuning of meantone (e.g. 7-limit [[CTE]]) | |||
* Whether it approximates a very simple n-[[Pythagorean comma]] meantone | |||
* Whether it is about equally sharp of [[3/2]] as some other listed temperament is flat | |||
* Whether it is close to exactly one [[just-noticeable difference]] away from 3/2 | |||
Occasional other comments may be included as well. | |||
=== Characteristics omitted === | |||
Dozens of tunings on this table are significant to [[negative harmony temperaments|negative harmony temperament theory]], enough that labelling them all individually would clutter the table. | Dozens of tunings on this table are significant to [[negative harmony temperaments|negative harmony temperament theory]], enough that labelling them all individually would clutter the table. | ||
Every tuning on this table is close to some arbitrarily large edo, but labeling them beyond [[100edo]] would clutter the table. | |||
