Atonal theory magic trick of the day

[deflatcb]

Something I figured out today:

Attention all composers!  If you have an AIT (0146 or 0137 - doesn't matter) and you want to move to a different AIT with a minimal amount of motion, keep the tritone (ic6) invariant and transpose just one of the two remaining pitches by a tritone.  Presto chango!  By moving only a single tone, your old 0146 is now an inverted 0137 - OR your old 0137 is now an inverted 0146.

Works every time.

Enjoy!
