A comma (the actual punctuation mark ",") is spoken as "add", thus C,v7 is "C add-down-seven". The only exception is when a comma separates two numbers, as in C4,7 which is "C four-seven". A comma is written, and "add" is spoken, whenever not doing so would cause confusion with another chord. C^,~6 is clear without a comma or an "add" if limiting oneself to 31edo. However, some edos like 58-edo have an upmid 3rd and 6th, and C^~6 would be P1 ^~3 P5 ^~6.

Note that 4:5:6:7 = C E G vBb is named C,v7 not Cv7 because Cv7 is an alternate name for C~v7. To get a shorter name for this important chord, one could call it a harmonic7 chord, or one could borrow from [[color notation]] to call it a har7 chord, written Ch7. Names for subharmonic chords can be similarly shortened.

A punctuation comma (",") is spoken as "add", thus C,v7 is "C add-down-seven". The only exception is when a comma separates two numbers, as in C4,7 which is "C four-seven". A comma is written, and "add" is spoken, whenever not doing so would cause confusion with another chord. C^,~6 is clear without a comma or an "add" if limiting oneself to 31edo. However, some edos like 58-edo have an upmid 3rd and 6th, and C^~6 would be P1 ^~3 P5 ^~6.

Note that 4:5:6:7 = C E G vBb is named C,v7 not Cv7 because Cv7 is an alternate name for C~v7. To get a shorter name for this important chord, one could call it a harmonic7 chord, or one could borrow from color notation to call it a har7 chord, written Ch7. Names for subharmonic chords can be similarly shortened.

Extended jazz symbol set

No*ie's original proposition (2024-03-02).

No*ie proposes the following symbols:

Chord quality Symbol Comments
Inframinor I The horizontal and vertical bars of the letter I may be drawn to scale with the subminor symbol for more visual consistency
Subminor = Akin to two parallel minus signs
Minor −
Neutral ◻
Major △
Supermajor ▲
Ultramajor U The letter U may be drawn with horizontal and vertical bars for more visual consistency with other symbols
Harmonic seventh H7
Diminished ∘
Subdiminished / sin(bv5) ●
Half Diminished / m7(b5) ∅
Half Subdiminished / sin7(bv5) ⦰
Augmented +
Superaugmented / saj(#+5) 王 (or *) Akin to the plus sign with two extra lines

These symbols can also be used with other tuning systems where these interval qualities are relevant.
