I think one of the great things about being a musician is that you never stop learning.
As a musician I'm kind of nomadic, Waldo-like. I show up in different places, and I'm witness to unbelievable things.
Jazz has been such a force in music, that any musician, including classical composers, have been influenced, and obviously performers, also.
When people ask me how they should approach performance, I always tell them the professional musician should aspire to the state of the beginner.
