''Stuff I'll add next; the numbers are just shorthand instructions for myself to help me know what to do, don't worry about them:''
There are at least hundreds, probably thousands, of [[rank-2 temperament]]s described. It can be difficult to know where to start.
 
This page is intended as that starting point. It does not aim to list every temperament. Instead it aims to list only the ones that are of high interest to a sizeable number of composers or theorists.
 
Composers and theorists disagree amongst themselves about what properties are desirable in a temperament, and you might over time find that you lean more towards one camp or another. This list arranges temperaments by their properties, allowing you the reader to seek out temperaments with whichever properties you value.
 
== So, which temperaments should I use to make music? ==
 
Ask 5 xenharmonicists, and you'll get 10 different answers. There are many different schools of thought within RTT (regular temperament theory).
 
Most would agree that a good temperament approximates some subset of [[just intonation]] relatively accurately with a relatively small number of notes.
 
What they disagree on is ''how'' accurate is "relatively accurate", ''how'' small is "relatively small", and ''which'' JI subsets are interesting enough to be worth approximating.
 
 
For example:  
 
 
'''Xenharmonicist A''' might argue that an error less than 15ish cents on most intervals, and less than 5 cents on the really important ones (like the perfect fifth and the octave), is accurate enough.
 
And they might argue that 25 notes per [[equave]] is the most that is practical, any more than that is too cumbersome.


''Hanson Me 20 5lim''
They might argue that nobody can hear the harmonic effect of prime harmonics higher than 11.


''Valentine H 20/30 5,7,11''
And they might argue that there's no real reason to use subgroups that are missing primes 2 or 3, because those primes are so important to consonance.


''Superpyth L 20/30 5,7,11,13''


''Godzilla L 20/30 7, 11''
'''Xenharmonicist B''' might argue that the error must be less than 5ish cents on most intervals, anything further out than that sounds out of tune to them.


''Augene L 30 7, 11, 13''
They might argue that it's perfectly possible to learn up to 50 notes per [[equave]].


''Didacus Me 20 No3''
They might argue that they can hear the subtle, delicate effect of prime harmonics up to 23.


''Orgone Me 20 No3''
And they might argue that subgroups like 3.5.7.11 and 2.5.7.11 are the most fertile ground for new and exciting musical exploration.


''Slendric Me 20 No5''


''Bleu Me 20 No5''
Neither xenharmonicist can be objectively shown to be right or wrong. There is an amount of science to this, but there is also a lot of personal subjectivity. Ultimately it's up to you to decide what features you think are important in a temperament.


It might help to compare these temperaments to [[12edo]], a.k.a. the familiar 12-tone equal temperament which most modern music is tuned to by default. 12edo has, of course, 12 notes per equave, which makes it fairly small by temperament standards (but not abnormally so).


There are at least hundreds, probably thousands, of [[rank-2 temperament]]s described. It can be difficult to know where to start.  
It can be interpreted as a low-to-medium accuracy 5-limit temperament where the most important intervals (the fifth and octave) have an error less than 3 cents, while other notable intervals (like the thirds and sixths) have an error of about 14 cents.


This page is intended as that starting point. It does not aim to list every temperament. Instead it aims to list only the ones that are of high interest to a sizeable number of composers or theorists.
Alternatively, it can be interpreted as a high-accuracy 2.3.17.19 subgroup temperament, where all of the intervals have an error less than 5 cents.


Composers and theorists disagree amongst themselves about what properties are desirable in a temperament, and you might over time find that you lean more towards one camp or another. This list arranges temperaments by their properties, allowing you the reader to seek out temperaments with whichever properties you value.
So that should provide a point of comparison to help measure these other temperaments against.
