<u>Alterations are always in parentheses</u>, additions never are, e.g. z7(zg5) and z,y6. An alteration's degree must match a note in the chord, e.g. Cz7(y6) is invalid. But an exception is made for sus chords, where degree 2 or 4 alter the 3rd. The sus note defaults to wa. A [[6:8:9|6:8:9 chord]] could be written C(4), but the parentheses rule is relaxed to allow the conventional C4. Likewise [[8:9:12]] is C2. But if the sus note isn't wa, parentheses must be used. Thus {{nowrap|w1 z4 w5 {{=}} C(z4)}} {{nowrap|{{=}} "C zo-four"}}. More examples:   

Omissions are indicated by "no". The za [[Hendrix chord]] is Ch7z10no5. (To write it as a sharp-9 chord, use qu: Ch7zq9no5.) A no3 tetrad can also be written as a 5 chord with an added 6th or 7th: Cy6no3 = C5y6, and Cz7(zg5)no3 = C(zg5)z7.   

<u>All wa chords can be named conventionally</u>, since wa is the default color. Thus {{dash|w1, w3, w5}} is both Cw and Cm. And {{dash|w1, Lw3, w5, w6}} is both CLw6 and C6. For aesthetic reasons, the conventional name is preferred only when neither "M" nor "m" appears in the name (since color notation doesn't use major/minor). This is especially true if the chord includes non-wa notes: {{dash|w1, w3, w5, y6}} is Cw,y6 not Cm,y6.   

In relative notation, the previous example becomes Iy - yVIg - IVy - Vy,w7, spoken as "one yo, yo-six gu, four yo, five yo wa-seven". Never use lower-case roman numerals for minor chords: ii becomes IIg or IIz. A IIIy chord has a w3 root, which is 32/27 not 81/64. The latter would be a LwIIIy chord (use L and s, not # and b; #IIIy is invalid).  

(Occasionally, the 6th or the 7th may be La or sa. For example, the wa scale has a wa 3rd, because the 3rd of the scale always matches the scale name exactly. The 6th and 7th default to a perfect 4th/5th from the 3rd, so the 6th is sa, not central. Thus the wa scale is minor, and the Lawa scale is major.)   

Analogous to the relative and parallel major or minor, one can modulate to relative gu, parallel ru, etc. Modulating from a yo key to the relative gu means using gu chords on yo roots. Modulating from yo to the parallel gu means using gu chords on <u>wa</u> roots. Going from yo zo to the relative gu means using chords with gu and/or ru in them on yo roots. Going to the relative ru means using the same chords on zo roots. Going from yo zo to the parallel gu ru means using the same chords on wa roots. One can also modulate '''fourthward''' or '''fifthward''', abbreviated '''4thwd''' or '''5thwd'''. Modulating in either direction is modulating '''waward'''. Modulating from a yo key to the relative gu, and perhaps from there to the parallel yo is modulating '''yoward'''. A root movement by a yo interval (e.g. Iy - yVIg) is a yoward move. Likewise, there's '''guward''', and '''y<u>a</u>ward''' includes both. Likewise, there's '''zoward''', '''ruward''', '''zaward''', '''iloward''', etc.   

{{Main | Color notation/Temperament names}}

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 [[Naming Rank-2 Scales using Mode Numbers]].           

Color notation merely renames ratios more conveniently, and strictly speaking, it only applies to just intonation. However, ratios are often used to loosely describe intervals in [[EDO | edos]], and colors can be used as well. A more precise notation uses [[Ups and Downs Notation | '''ups''' '''and''' '''downs''']] (^ and v) as "virtual colors", accidentals that always map to exactly one edostep. Ups and downs are used on the score just like color accidentals are. Notes are named e.g. up C sharp = ^C#. [[Sharpness | Sharp-1 and flat-1]] edos don't require ups and downs.                 

[[Tour of Regular Temperaments | Rank-2 temperaments]] can be notated with ups and downs as well. Plain and mid are also used in this context. Certain temperaments require an additional pair of virtual colors, '''lifts''' and '''drops''' (/ and \). Notes are named lift C = /C, downdrop F sharp = v\F#, etc. Intervals are named drop 4th = \4, uplift major 3rd = ^/M3, etc. Plain means neither up nor down nor lifted nor dropped. There may be upmid or liftmid intervals. Chords are named C-up add lift-seven = C^,/7 = C ^E G /Bb, C uplift-seven = C^/7 = C ^/E G ^/Bb, etc. See [[Pergen | pergens]].  

'''Over''' = prime in the numerator. '''Under''' = prime in the denominator. '''All''' = over, under or neither: wa = 3-limit, ya = 2.3.5, yaza = 2.3.5.7. '''Exponent''' = repeated syllable: triyo = yoyoyo = 125-over.
