I went to school for jazz for two years and to put what I’m saying most clearly I present this interaction:
During combo one day we began learning a Miles Davis song, I cannot remember which one unfortunately, and I suggested a slight alteration to our arrangement as I thought it’d sound better with the way we’d been playing it to which my teacher responded “do you really think you can come up with something better than Miles?”
Now maybe I couldn’t but I think Mr. Davis would respect it for trying to push something forward or even being willing to try. Whenever I’ve suggested that jazz can still be original and you can bring your own flair to it, I’m met with general responses of “okay but you need to respect the tradition..” and yes, you do, but since when was being creative and original not part of that? It’s not like I’m reinventing the wheel, I just do things slightly different.
I ran into this and similar arguments so many times that it created a genuine disliking for the way they teach jazz in school, at least that one. I also recall being told “we’re not here to make you artists, we’re here to get you a job” and it’s understandable but also extremely sad. Surely there’s a balance somewhere in there.
