Three little riffs that could be developed further: Schoenberg's comment on Slonimsky, Harbison on classical music "in the moment", Coltrane's harmonics as something resembling feedback.
On the back of Slonimsky's
Thesaurus of Scales and Melodic Patterns is a blurb by Schoenberg that seems sort of hautily dismissive:
I looked through your whole book and was very interested to find that you have in all probability organized every possible succession of tones. This is an admirable feat of mental gymnastics. But as a composer, I must believe in inspiration rather than in mechanics.
This reveals that Schoenberg, far from being a mathematically-inspired composer or a careful watchmaker, was a composer who wrote only when feeling the heat of inspiration. He was rather impatient with systems and with slow working-out. He understood himself to be a master who could work quickly and intuitively when he grasped the big design. There had to be a method, a purpose, and perhaps even a place in the world of music at the time, but once that was clear to him it was only a matter of working out the details.
For all his inventor's streak, Schoenberg was an expressive composer in the grand manner, not someone who was satisfied to have constructed something just for the sake of trying something out. Tone-series and even principles of design would have little intrinsic interest for him. This would tend to have a bad effect on all but the best students. Best not to try to be like the master.
A gem like the Thesaurus will be dismissed by people for all kinds of reasons, including the perverse reasons of a few geniuses and the more common complacency of the hacks. Schoenberg's comment isn't quite as egotistical as it first seems. Or rather, it is, but he was right -- the row doesn't mean much by itself. It requires a whole musical and social context to give it meaning.
---------------
I've never been a huge fan of John Harbison's music, but he said something interesting in a Globe interview last week. It was something to the effect that classical music can and should be something
for the moment, for the daily activity of making music here and now because you're alive, not because it will satisfy some Eternal Standard. I've embellished his comment. It comes as a good correction to my thinking. Because of the way I've worked -- making recordings that are the final product -- I've tended to think of my music as consisting of fixed objects that have their (trivial, unimportant) place in music history. Maybe it's better to think rather that they are just the records of what I was doing at the time, and to proceed that way in the future.

Coltrane
It's odd to think that at one time, Coltrane's influence loomed no larger than other jazz players, and so someone could write a serious scholarly article attempting to discuss Coltrane, Cecil Taylor, Anthony Braxton, and Ornette Coleman as if they were all part of one thing, the same thing. Gunther Schuller seemed more approving about Ornette Coleman's approach than he did about Coltrane's.
The way it turned out: Almost everyone wanted to sound like Coltrane. About half a dozen people tried to play like Ornette. Braxton and Taylor remained art-school musicians.
I despair at trying to explain the layered complexities of Coltrane's tonal approach. The subject I want to mention briefly is that part of Coltrane's still-tonal playing, that part of his solos, where he begins to go "out" -- to use pitches outside the normal scales.
The idea is that he adds harmonics to various kinds of chromatic or scale-embellishment. A harmonic of a note is some multiple of that note's frequency: It is distant in melodic space but adjacent in harmonic space.
This kind of overtone-jumping usually occurs in the most heated passages and was something he aspired to. It was something impossible, like playing his complete scales on a tune that Miles called at twice the original tempo. Attempting to play the impossible was an integral part of his whole approach to music.
It is formally and sonically not too far from guitar feedback. I think it's no accident that Coltrane was trying to harnass the power of something like the sound of feedback at a time when feedback on the electric guitar was just starting to happen.
