The heart of a music is its rhythm. The heart of rhythm section music is the rhythm.

I worry more about the marketing that's taken hold since the 70s. The Jazz era, the Swing era, those were huge. Entire decades were named for music. In the 1940s - after World War II - changes in taxation, ballrooms closing, people moving to the suburbs, and the onset of target marketing and the confusion of commerce with art caused some things to happen as a result that have taken us away from jazz and what jazz offers us.

What takes its place is very dry education. And the tools that actually can teach you - singing and playing, learning how to participate with other people, spiritual richness - are replaced with a big emphasis on how to memorize things. That's such an incomplete education. Survival of the fittest used to mean being bigger and stronger.

Walt Whitman's "Leaves of Grass" is still in print. They're debating right now over Mark Twain. He's still available. Winslow Homer can still be seen. Our arts are - they're there. We got to go get them and understand that this is an important legacy for our country.

Having heard Clifford Brown play all those fast runs, I used to really practice Clarke trumpet exercises all day long so that I could play fast. That's all I wanted to do. I was like a child with a toy.
