22edo chords

22edo contains a huge wealth of harmonies to explore. It has not only 5-limit major and minor but also various 7-limit and 11-limit chords.

Triads

22edo contains many triads. This list is by no means an exhaustive one, but it highlights some common and interesting ones.

Seventh chords

While triads show promise, the real fun in 22edo is tetrads. There is a wealth of interesting tertian-based tetrads.

Various 22edo 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.

Highly implausible chords are named as a more plausible homonym, e.g. 0–9–14 = C4(^5) becomes 9–14–22 = Fm, where "a" stands for augmented and "d" stands for diminished.

A punctuation comma (",") is spoken as "add", thus Cv,7 is "C-down 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.

4:5:6:7 = C vE G Bb is named Cv,7. 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.
