I just meant that, you know, it being the first chapter in a book called
"Basic Atonal Theory" suggests that it's a well-known and standard sort of
thing, and so I thought you would have known of the model, not necessarily
from this particular book--which, though it's actually quite carefully put
together and even sufficiently rigorous, was designed as a text-book
palatable to music undergrads, and not for bad-ass PhDs in maths!

Well I'm not sure, either, that he "defines" pitches as integers--that
sounds wrong. He doesn't attempt an ontological examination of what
pitches actually *are*, he assumes you know what pitches are, and starts
by *associating* integers to pitches, then labels pitches by the integer
associated to them, choosing middle C arbitrarily as zero. The pitches of
12-tet are ordered and equally spaced so it seems pretty natural to me
that you'd think of modelling them with integers. Then you can say the
interval between two pitches m and n is the difference |m-n|, etc etc.

And it's not dependent on notation--sing me a song, I'll tell you what the
pcs are, no notation involved.

You know what things are unless you are doing pure math, where you
define what they are. This is applied math, but I think that works
better if you give clean definitions here also. What happens if I make
assumptions about what you mean by "pitch" and they turn out to be
different assumptions that yours? I'm still trying to digest the idea
that "pitch" is a feature of a score, not of any actual sound.

What if I'm singing along with Paul and he's playing a 22-et guitar?
