I remember when I wrote a piece, "Blood on the Fields," it was a while ago, it was about slavery and about two characters, and I studied so much of music, I would always go back to the original documents, and as much as I can get original chants and slave chants and different type of beats and rhythms and ring shout.

Young kids are always singing and painting. When you get to that second and third grade level, you're supposed to put all that aside.

Jazz music is America's past and its potential, summed up and sanctified and accessible to anybody who learns to listen to, feel, and understand it. The music can connect us to our earlier selves and to our better selves-to-come. It can remind us of where we fit on the time line of human achievement, an ultimate value of art.

I hope it might help players have confidence in our own ways, and not to be afraid of them, as Bernstein showed - things like hoe-downs, fiddle songs, and the art of improvisation, and the New Orleans funeral tradition, and call-and-response church singing, and the fact that the blues run through everything. And in our relationship to European music, in that we don't have to imitate it, it's a part of us, inseparable.
