* Note that there are two Dorians for each chirality, Bright and Dark Dorian.

* (*) We take these as the default LH Aeolian and RH Mixolydian because they can be dechiralized (see below). The adjectives "brightened" and "darkened" are modifications that flatten the default modes by a comma step; these modes have no dechiralized equivalents.

=== ~~Dechiralized~~ modes ===

=== Ambi modes ===

By taking the pitches of both chiralities corresponding to each diatonic mode, we obtain the achiral scale LSCSLMLSLM, where c = L − s. This is a stretched version of the [[blackdye]] scale with the same step ratio (with the L in the "SLS" of blackdye made smaller). There are 8 dechiralized modes that result from changing an occurrence of SL and LS in it to SCS (on the same root as the original chiral modes).

By taking the pitches of both chiralities corresponding to each diatonic mode, we obtain the achiral scale LSCSLMLSLM, where c = L − s, termed ''ambi'' diasem (after ''ambidextrous''). This is a stretched version of the [[blackdye]] scale with the same step ratio (with the L in the "SLS" of blackdye made smaller). There are 8 dechiralized modes that result from changing an occurrence of SL and LS in it to SCS (on the same root as the original chiral modes).
