[[Color notation]] can name every regular temperament. The name is the same as that of the comma(s) tempered out, but | [[Color notation]] can name every regular temperament. The name is the same as that of the comma(s) tempered out, but using an alternate format designed for commas. This format omits the degree (unison, 2nd, etc.). For example, [[Semaphore]] tempers out the zozo 2nd and is called the Zozo temperament. The name of the comma and the temperament is always capitalized, to distinguish it from the color. Thus zozo refers to all zozo ratios, whereas Zozo refers to one specific zozo ratio, 49/48. | ||
The color defines a lattice row, and the magnitude (large, small, etc.) defines a '''segment''' of that row. A name without a magnitude, like Zozo, refers to the central segment. Each segment contains 7 ratios. The comma that is tempered out is the smallest in cents of those 7. | The color defines a lattice row, and the magnitude (large, small, etc.) defines a '''segment''' of that row. A name without a magnitude, like Zozo, refers to the central segment. Each segment contains 7 ratios. The comma that is tempered out is usually the smallest in cents of those 7. If not, '''-bi''' or '''-tri''' is added to the end of the name to indicate that the comma is the 2nd or 3rd largest ratio in that segment, e.g. [[Mavila]] = Layobi. Any comma smaller than 256/243 = 90¢ is guaranteed to be the smallest ratio in its segment, thus -bi and -tri are only used for very large commas. | ||
Some 5-limit examples, sorted by color depth. Many more examples can be found on the comma pages [[Comma|here]], [[Medium commas|here]], [[Large commas|here]] and [[Unnoticeable comma|here]]. | |||

Exponent syllables like bi or tri are always unaccented. To emphasize the prime limit, the first occurrence of the highest prime is always accented: Bi'''r<u>u</u>'''yo, Bi'''<u>zo</u>'''zogu. In longer names, the 1st occurrence of sa/la and/or of lower primes may also be accented: '''Sa'''sa-'''gu'''gu, '''Zo'''zotri'''gu'''. | |||
Sometimes the smallest ratio in a segment is some other comma raised to some power. For example, the smallest ratio in the central segment of the zozogugu row is 441/400. But since this is (21/20)<sup>2</sup>, tempering it out would simply result in the Zogu temperament. Thus there is no Bizogu temperament, although there is a Bizogubi one. | Sometimes the smallest ratio in a segment is some other comma raised to some power.

Tempering out 128/125 from 2.3.5 makes Trigu. Since 128/125 is a two-prime comma, it implies an edo, and Trigu can unofficially be thought of as 3-edo plus wa. | Tempering out 128/125 from 2.3.5 makes Trigu.

Temperaments | Temperaments are abbreviated with "T": Zozo = zzT, Triyo = y<sup>3</sup>T, Gu & Rugu = g&rgT, Layobi = Ly#2T, Sawa + ya = sw+yT, Wa-41 + ya = w-41+yT, Gu + zala = g+z1aT, and Biruyo Nowa = rryy-wT. | ||
