Polytonal and polymodal mirror harmony via scales
Each mode of the major scale has it’s mirror [modal] opposite because the whole diatonic scale system can be symmetrically inverted.
Inverted Symmetrical Reflection. The intervals are the same both in harmonisation and contrary motion.
OR:
Lydian-Locrian=Mirror pair
Ionian-Phrygian=Mirror Pair
Mixolydian-Aeolian=Mirror pair
Dorian-Dorian=Palindromic [Produces the same scale either way].
