Boomsliter and Creel are re-born! And are more robust. Mr. Akkoc, your
work sounds very exciting to me. At first look I do agree with Paul Erlich
that this approach is applicable to Western (and other) music.

If only all music theory and psychoacoustics were as keen on observing what
musicians do (rather than having the musicians do something dreamt up for
an experiment) as you seem to be!

And I shall surmise exactly the opposite.

There may be a small "bag of tricks" like this at work, but I suspect they
can be safely ignored.

Vertical context is surely a big deal, but melody alone should have it's
own wonders to disclose, and these should be nailed down before moving on
to bigger game, IMO.

This is the booty! John, do you happen to know which paper this is in, or
R's catchword for it?

Mr. Lumma,

Thank you for your complimentary remarks on my work. I totally agree with
your comment "Vertical context is surely a big deal, but melody alone
should have its own wonders to disclose, and these should be nailed down
before moving on to bigger game,...".

In my humble judgement Turkish music has achieved multi-dimensionality,
a form of musical "richness", through multi-modality. There seems to be a
very intricate grand structure made up of 120 some `maqam's, interconnected
in sophisticated ways, making up the `universe' for this music. An individual
aspiring to become a master of this kind music has to learn and fully
comprehend the musical "architecture" of the said structure. This is an
extremely demanding proposition on the part of the apprentice, requiring
many decades of training with persistence and dedication. Adding vertical
context to such a structure, as some theoreticians have tried to do in the
past, could be very risky if not totally inappropriate.

Regarding a quote from Chalmers, the term "equivalence class" has a very
positive ring to my ears.
