Over the years I've had strong friendships with many priests. As a matter of fact, a group of Christian leaders from the National Council of Churches came to my house in the 1950s to ask me to write music for a Mass. I didn't think I was ready at that time. So, in a sense, I guess joining the church and writing the Mass was a culmination of a long journey that is still going on.

My dad was the manager at the 45,000-acre ranch, but he owned his own 1,200-acre ranch, and I owned four cattle that he gave to me when I graduated from grammar school, from the eighth grade. And those cows multiplied, and he kept track of them for years for me. And that was my herd.

My mother Elizabeth Ivey Brubeck was a pianist who studied with Dame Myra Hess and Tobias Matthey. As a child in California I used to listen to her play Chopin.

When you hear Bach or Mozart, you hear perfection. Remember that Bach, Mozart and Beethoven were great improvisers. I can hear that in their music.

Duke Ellington, Art Tatum, and many other great jazz musicians objected to their music being called jazz. While the outside world may want to put a label on it, those who create it think of it just as music, and tend not to classify it.

Art may not have the power to change the course of history, but it can provide a perspective on historical events that needs to be heard, even if it's seldom heeded. After all the temporary influences that once directed the course of history have vanished, great art survives and continues to speak to each generation.

I started growing up in a hurry and taking a lot of the philosophy I'd heard from church as a kid a lot more seriously - especially the Ten Commandments - and wondering how 'Thou shalt not kill' could be so absolutely ignored. It took me until I was in my 40s to write what I was thinking as a young soldier.
