Many on the list, primarily Bill Sethares (are you familiar with his work?),
have the opposite viewpoint. I try to emphasize both, since both seem very
important in defining consonance as I hear it. A third property is close to
combination tones in its implications for consonance but is perhaps more
important since it does not require loud volumes: the "virtual pitch"
property; i.e., the closer the chord is to a harmonic series, the more
clearly a "root" will be perceived (by the same means by which we hear a
harmonic series as a single pitch), and the more consonant the chord will
be.

>2.) With regard to subsets of the scale: Unlike Pierce's obviously

>3 4 6 7 8 10 12 (13). I like the "Gamma" best, but that is a personal view.

I'll have to try these different modes out! As you may have read, Gary
Morrison and I have both experimented with this tuning and fail to hear any
3:1 equivalence. We hear the nearest approximations of 2:1 and 4:1 in the
scale as being the closest equivalences, even when square waves are used. Do
you think Enrique is right that we have been brainwashed and just need to be
re-brainwashed, or is the experimental evidence for equivalence at a
(slightly stretched) 2:1 valid? Many studies have found evidence for octave
equivalence in mammals. . .

Perhaps your best bet for that may be Bart Hopkin?
