Milk in a mother's breast-that's cool. Milk in a mouth-that's cool too. But milk in my trumpet? Not so cool. I have to play that thing.

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.

Music is the art of all the invisible things that are real. Art, emotion, spiritual essence, consciousness - these things are hard to prove. Music helps you to focus on your sound. We understand that for very young kids.

I get so much from having the opportunity to interface with the younger people and to bring information to them and to represent our culture and our way of life. The feeling and the warmth and the love, it's unbelievable. The type of exchange that goes on between students and teachers or visiting people who are doing master classes, and not just when they're musicians. Even general classes, when the students are not necessarily musicians.

When I did the Abyssinian mass, I went through the whole history of the church music and the gospel music, even with the Anglo American hymns, the Afro American hymns, the spirituals and how it developed, up to Thomas Dorsey and the Dixie Hummingbirds, going through the history of the music, jazz musicians.

There's always the cliche of the choir shouting and clapping. OK, you have to do that, but there's also introspective parts, parts where you just follow someone that's preaching. There's lots of different emotions and moods that a service requires.

I'm not a person who writes really abstract things with oblique references. I look at abstraction like I look at condiments. Give me some Tabasco sauce, some ketchup, some mayonnaise. I love all of that. Put it on a trumpet. I've just got to have the ketchup and Tabasco sauce. That's my attitude about musical philosophy.
