Kite's color notation/Temperament names

Color notation can name every regular temperament. The name is the same as that of the comma(s) tempered out, but without the degree (unison, 2nd, etc.). The color defines a lattice row and the magnitude (large, small, etc.) defines a segment of that row. Each segment contains 7 ratios. The comma that is tempered out is assumed to be the smallest in cents of those 7, excluding any ratio that is a multiple of another comma. For example, the smallest ratio in the central segment of the zozogugu row is 441/440. But since this is (21/20)², tempering it out would simply result in zgT. Thus zzggT refers to tempering out the next largest ratio, 784/675 = 259¢.

If the comma is the 2nd largest valid ratio in the row segment, the temperament name ends with "2". For example, Schismatic is LyT and Mavila is LyT2. Likewise, LyT3 would temper out the 3rd largest ratio. Any comma ≤ 90¢ is guaranteed to be the smallest ratio in its segment.

Words like large, small, double, etc. are abbreviated, to make the names a reasonable length.

• Double = bi- ("bee"), triple = tri- ("tree"), quadruple = quad-, quintuple = quin-, septuple = sep-
• Large = la-, small = sa-, double large = lala-, triple small = trisa-, etc.

Some 5-limit examples, sorted by color depth. Many more examples can be found on the Commas page.

1. Schismatic = Layo = LyT, Mavila = Layo-two = LyT2, Superpyth = Sayo = syT. Meantone = Gu = gT, Father = Gu-two = gT2.
2. Dicot = Yoyo = yyT, Immunity = Sasa-yoyo = ssyyT. Bug = Gugu = ggT, Diaschismic = Sagugu = sggT, Beatles = Sasa-gugu = ssggT.
3. Porcupine = Triyo = y³T. Augmented = Trigu = g³T, Laconic = Latrigu = Lg³T, Misty = Sasa-trigu = ssg³T.
4. Negri = Laquadyo = Ly⁴T, Tetracot = Saquadyo = sy⁴T, Vulture = Sasa-quadyo = ssy⁴T. Diminished = Quadgu = g⁴T.

Multipliers like bi-, tri-, etc. can be combined: 6-fold = tribi-, 8-fold = quadbi-, 9-fold = tritri-, 10-fold = quinbi-, 12-fold = quadtri-, 14-fold = sepbi-, 15-fold = quintri-, 16-fold = quadquad-, etc. Higher primes use their color word, but with the suffix -e for exponent:

• 11-fold = le- ("leh"), 13-fold = the- (unvoiced "th"). 17 = se-, 19 = ne-, 23 = twenty-the-, 29 = twenty-ne-, etc.

Even with these abbreviations, temperament names can get quite long. To make them quicker to say, and to make the words easier for non-Anglophones, "bee" and "tree" are preferred over "bye" and "try". If the comma's ratio has N digits, the temperament name will usually have N, N-1, N+1 or occasionally N+2 syllables.

La means large and also 11-all. The meaning will almost always be clear from context, however "this piece uses la notes" is ambiguous. To clarify, one should say either "large notes" (fifthward notes) or "ila notes" (11-limit notes). Likewise, sa also means 17-all, and "sa notes" should become either "small notes" or "isa notes".

La is also the La note in solfege, and Sa is the tonic in saregam. The meaning will always be clear from context. Notes are never large or small. In fixed-do countries, the chord ALw (81/64 3rd) is "La lawa".

If the comma is wa, an edo is implied. The temperament is named after the edo, not the wa comma. 2.3.5.7 and the pyth comma and 225/224 is 12edo&ryyT. If the comma(s) don't include every prime in the subgroup, some primes are untempered. These primes are added with plus: Blackwood is 5edo+yT = 5-edo plus ya. The 2.3.5.7.11 subgroup with 81/80 tempered out is g+z1aT = gu plus zala.

The temperament name indicates the prime subgroup and the rank of the temperament. For example, ryyT (Marvel) is rank-3 because it has 2 explicit colors ru and yo and 2 implicit colors wa and clear, and 4 colors minus 1 comma = rank-3. Edos count as commas, but plusses don't. Both 12edo&ryyT and 5edo+yT are rank-2. Primes 2 and 3 are assumed present in the temperament even if they are not present in the comma. Biruyo is rank-3 and biruyo nowa is rank-2.

There are two obvious ways to name multi-comma temperaments. The odd name minimizes the double odd limit of the comma set, and the prime name minimizes the number and size of the primes used by each comma. The odd name for 7-limit Pajara is rryy&rT, and the prime name is sgg&rT. Often the two names are identical, e.g. y³&rT. The odd name is often shorter, and usually indicates commas more likely to be pumped. The prime name shows relationships between bicolored rank-2 temperaments better. The question of which name to use is not yet fully resolved.

Rules for naming remote colors and extreme magnitudes

There can be more than one way to name a comma. To avoid duplicate names, there are naming rules.

• Colors are always listed highest primes first.
• Multipliers affect all subsequent syllables until the -a- delimiter occurs: trizogu = z³g³, but trizoagu = z³g.
• The "a" in la and sa acts as a delimiter: trilayo = L³y and trilatriyo = L³y³
• [Is this rule needed?] Multiplier syllables fuse into one multiplier word: tribizogu = (tribi) x (zogu) = z⁶g⁶, not (tri) x (bizogu).
• Avoid using the -a- delimiter if possible: z⁴gg = bizozogu, not quadzo-agugu

Therefore if the name starts with a multiplier word, and there's no -a- delimiter, that first multiplier word indicates the color GCD and thus the pergen's split(s). e.g. bizozogu = (P8, P5/2, /1). In the list below, an asterisk marks cases where this isn't possible, and the GCD is hidden.

Hyphens are used to make the name easier to parse. There are strict rules for hyphenation, to ensure uniformity. Hyphens are inserted before every -a- delimiter and/or after the magnitude (after the final la- or sa-). However, the hyphen after the magnitude is omitted if it would create a subunit of 1 syllable. Thus triyo, sagugu and lalagu are unhyphenated.

Gugu is generally preferred over bigu (zogugu not zobigu). But bizo is preferred over zozo sometimes to indicate the GCD, e.g. bizogugu not zozoquadgu. Likewise, tribigu is preferred over trigugu, as is quadbigu over quadgugu, etc.

There follows examples of remote colors, for illustration. These examples don't all correspond to musically useful temperaments!

Tricolored examples

if lu is not doubled or tripled, it just gets tacked onto the beginning:

1uzgg = luzogugu
1uzzgg = lubizogu
1uzzg = luzozogu
1uzg³ = luzotrigu
etc.

1uuzg = luluzogu
1uugg = bilugu
1uuzgg = luluzogugu
1uuzzzgg = biluzogu
1uuzzg = biluzo-agu

1uuzg³ = luluzotrigu
1uuzzg³ = biluzo-atrigu
1uuz³g³ = lulutrizogu
1uuz³gg = lulutrizo-agugu
1uuz³g = lulutrizo-agu

1u³zzg³ = trilu-azozotrigu
1u³z³g³ = triluzogu
1u³z³gg = triluzo-agugu
1u³z³g = triluzo-agu

If the 2nd color could be merged with either the 1st color or the 3rd color, but not with both, it merges with whichever one has a larger exponent. Thus in these examples, zo merges with the tripled color, not the doubled color:

1uuz⁶g³ = lulu-trizozogu, not bilutrizo-atrigu
1u³z⁶gg = triluzozo-agugu, not trilu-atribizo-agugu

if tho is not doubled or tripled, it just gets tacked onto the beginning:

etc.
