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.

The first choral music I remember hearing was Handel's 'Messiah' when the Mormon Tabernacle Choir broadcast it over the radio.

Don't be a perfectionist... leave that to the classical musicians.

The source of inspiration can be any of the things:deep emotional experiences - say, romantic love or spiritual contemplation.I think such rare moments come only when you have total concentration. You are consumed in and by the music. I guess you could say that it is akin to contemplation. In order to reach this desirable state of mind you have to rise above the environment you're in at that particular time - a bad piano, glaring stage lights, or the attitude of the audience. Sometimes the inspiration of the other musicians you're playing with helps you reach this stage.

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.

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.

And there is a time where you can be beyond yourself. You can be better than your technique. You can be better than most of your usual ideas. And this is a whole other category that you can get into.
