It makes sense if you expect to build chords from the lowest frequency
to the highest. But Partch implies that we should build chords by
increasing their limit rather than their frequency.

Those would be 9-limit chords.

Sorry, I did mean otonal/utonal. Yes, otonal and utonal 2:3 create
dyads of the same size, but, like Margo, I consider the 'power chord'
the basic sonority of the 3-limit, since it is saturated. 2:3:4
otonal, 1/(2:3:4) utonal. Using scale degree numbers here was also
a bad choice on my part. Anyway, I do find the difference between
these two "trines" similar to the difference between other saturated
otonal/utonal pairs through the 9-limit.

Any consonance of odd-limit x with significantly less tonalness than the
saturated x-limit otonal sonority.

It's really no big deal, and perhaps we should leave the definition of
minor alone. I simply suggest that the property above can be heard, in
a variety of different consonances, as a _quality_, and that this quality
has something to do with how we percieve music written in the major and
minor modes of the diatonic scale.

I seem to remember reading somebody suggesting that this quality had
to do with the way combination tones work in utonal v. otonal chords.
Same idea.
