Temperaments are named after the comma(s) they temper out. Commas are named using an alternate format that replaces the degree (unison, 2nd, etc.) with the suffix "-ma" (mnemonics: com'''ma''', or -is'''ma''' as in schisma and kleisma). The degree isn't needed because the comma is assumed to be the smallest interval in cents of that color and magnitude. For example, the guma is the smallest of the 7 central gu intervals, which is [[81/80]]. Tempering out the guma creates [[Meantone]] or Guti or gT, where "-ti" and "T" stand for temperament. [[2048/2025]] is the saguguma, abbreviated sggM, and [[Srutal]] is Saguguti or sggT. [[Porcupine]] is Triyoti or 3yT. | Temperaments are named after the comma(s) they temper out.

The logic for M and T being upper case is that in color notation abbreviations, nouns are always capitalized and adjectives are generally not. Color notation nouns: M and T, note names A B C D E F G, roman numerals I II III IV V VI VII, and degrees 1 2 3 etc. (L for large is an exception to this rule, because otherwise Ly7 would be ly7, which looks like a y7 chord on the tonic.) | The logic for M and T being upper case is that in color notation abbreviations, nouns are always capitalized and adjectives are generally not.

Some commas over 90¢ (but not all) are the ''2nd'' smallest interval in cents of that color and magnitude. These use the -bi- syllable. For example, [[Schismic]] is Layoti or LyT, but [[Mavila]] is Layobiti or LybT, where "-bi-" and "-b-" indicate it's the 2nd largest layo interval. Likewise 135/128 is named layobima or LybM. | |||
Most wa commas use yet another alternate format, e.g. [[Mercator's comma]] is 53wama or 53wM. The only exceptions are lawama (LwM = A1), sawama (swM = m2) and lalawama (LLwM = pythagorean comma). | Most wa commas use yet another alternate format, e.g. [[Mercator's comma]] is 53wama or 53wM.

Multi-comma temperaments have multiple commas in their name. [[Meantone family#Septimal meantone | Septimal Meantone]] is | Multi-comma temperaments have multiple commas in their name. [[Meantone family#Septimal meantone | Septimal Meantone]] is gu & ruyoyoti or g&ryyT, and [[Meantone family#Dominant | Dominant Meantone]] is gu & ruguti or g&rgT. Untempered primes are included with a plus sign. The 2.3.5.7 prime subgroup with 81/80 tempered out is Guti + za = gT+z, and [[Blackwood]] is Sawati + ya = swT+y. | ||
MOS and MODMOS scales can be named as e.g. Triyoti[8]. Individual modes can be named as 2nd Triyoti[8], 3rd Triyoti[7] b7, etc. See [[Genchain mode numbering]]. | MOS and MODMOS scales can be named as e.g. Triyoti[8].
