I found this article interesting, and think other's would as well. Conjuring Coltrane
I have been thinking a lot about how I affect my own tone, intonation, et al. lately, and I have been experimenting with what I can and cannot consciously change. I have been told several times about listening to other artists and creating my own sound concept. I have been assured that over time, subtle things will change to help move closer to that sound concept. The things that change regarding producing our sound concept are not so conscious, I think.The intangible alchemy at work in the interaction between a player's technique and anatomy and the instrument itself is a mystery still left to unravel.
The way a player adjusts their vocal tracts, or positions their tongue and holds their lips -- "all of these contribute in ways that are almost impossible to analyze from a purely physical point of view," Socolar said.
Well, but then it wouldn't have included anything about Duke and what an awesome and interesting university it is! We have to remember: this is written for an alumni magazine, and the sole purpose of the piece is to make alumni feel good about their alma mater and, hopefully, give some money. They're not trying to make any profound points about sax playing or Coltrane's music. I'm actually kind of impressed that they even included that bit at the end about how so many different things figure into a player's sound.The article should have started and ended with one paragraph ...
Using the same mouthpiece as Coltrane won't make you sound like him, Busch said. "It'll get you a little bit of the way, if you put in the work," Busch said. "But to really sound like John Coltrane, you have to be John Coltrane."
Looks like they came pretty close to doing just this.It was only about the question of whether it would be possible to make an extremely precise copy of a hand-picked example of a great vintage mouthpiece, that would sound a lot like that particular mouthpiece.
