* (*) 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. | * (*) We take these as the default LH Aeolian and RH Mixolydian because they can be dechiralized (see below).

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''). It ensures that every "supermajor third" (2L + S) in the scale has both major tone-minor tone and minor tone-major tone steps available. 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 ambi 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'').

The last two modes are exceptional because they begin and end in a C and thus do not result from a union-taking that preserves the tonic. | The last two modes are exceptional because they begin and end in a C and thus do not result from a union-taking that preserves the tonic. | ||
