24edo chord names

Revision as of 12:55, 22 January 2025 by ArrowHead294 (talk | contribs)

Various 24edo triads, 6th and 7th chords, named via ups and downs. Not meant to be exhaustive, but this list does demonstrate the basic rules for naming. ^M6 and vm7 are the same interval, and chords that use that interval can be named as either a 6th chord or a 7th chord.

vm3 m3 ~3 M3 ^M3 P4 ~4
Triad Cvm Cm C~ C C^ C4 C~4
~6 Cvm~6 Cm~6 C~6 C,~6 C^,~6 C4~6 C~4~6
M6 Cvm,6 Cm6 C~,6 C6 C^,6 C4,6 C~4,6
^M6

vm7

m7 Cvm,7 Cm7 C~,7 C7 C^,7 C4,7 C~4,7
~7 Cvm~7 Cm~7 C~7 C,~7 C^,~7 C4~7 C~4~7
M7 CvmM7 CmM7 C~M7 CM7 C^,M7 C4M7 C~4M7
^M7 Cvm^M7 Cm^M7 C~^M7 C,^M7 C^M7 C4^M7 C~4^M7

A punctuation comma (",") is spoken as "add", thus C^,7 is "C-up add-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 if limiting oneself to 24edo. However, some edos like 58-edo have an upmid 3rd and 6th, and C^~6 would be P1 ^~3 P5 ^~6.
