stuartk, you're not understanding me at all. When I hear a jazz group I can hear what is planned and when a musician goes into improvisation. That's a no brainer. Coltrane on "My Favorite Things" plays with his band the setup going through the melody a few times. Then he goes off on his own and flies high above the band who is just trying to keep up with him. I think I understand jazz a lot better than you think I do.
When L.A. had a commercial jazz station they would play what they called "soft" jazz. Sade, Diana Krall, maybe Davis playing "Some Day My Prince Will Come," and Trane playing something off his album "Ballads." I have an extremely abstract ear from listening to "modern" abstract classical. Shostakovich, Bartok, Stravinsky. In modern classical music the beat can be all over the place. Listen to Stravinsky's Rite of Spring.
I think in the jazz you're talking about nobody is on the beat yet it is implied and they all know where it is. And I know where it is. Coltrane often plays like that. And Davis on some of his later stuff. Bebop has syncopation.
In classical music, there is light classical, early classical with composers like Bach, and even up to Mozart. Then the Romantic Era begins with Beethoven and people see that as a more serious classical. And more difficult classical comes with 20th century and 21st century classical.
It would be so difficult for me to explain to you my understanding of music, but it begins in the Upper Paleolithic with people who lived in caves. I know nobody knows what that music sounded like, but I think I know why they made music. It was a spititual thing. Just like Coltrane, Sanders, and Davis felt their music was spiritual. And I believe the shamans and creative artists were women. But that's another argument.
I'll stop with this. But I think you're really underestimating my understanding of jazz.
