That seems sensible.
Here's a toughie, though. In some of the folk idioms of Georgia,
there is no octave-based scale: the music uses stacked major
tetrachords instead -
C D E F
F G A _B
_B c d _e
and so on (since this is vocal music, probably not much further,
but Georgian art-music composers have extrapolated it).
Anybody seen anything like that notated? If so, how's it done
in practice? (I could just phone Marina Adamia and ask, but hey,
that would take all the fun of guessing away).
