What I really have in my head, my imagination, my understanding of music, I never really get that out.

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.

The main three components are the blues, improvisation - which is some kind of element that people are trying to make it up - and swing, which means even though they're making up music, they're trying to make it up together. It feels great, like you're having a great conversation with somebody.

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.

In Jazz, improvisation isn't a matter of just making any ol' thing up. Jazz, like any language, has its own grammer and vocabulary. There's no right or wrong, just some choices that are better than others.

Grace Kelly plays with intelligence, wit and feeling. She has a great amount of natural ability and the ability to adapt. That is the hallmark of a first-class jazz musician.

The first jazz musician was a trumpeter, Buddy Bolden, and the last will be a trumpeter, the archangel Gabriel.
