With a piece of classical music by Haydn, Mozart, or Beethoven, on first listening I'm referencing it with other pieces by them that I know. I think that most people do this - they listen to pieces through the filter of pieces they already know.

Very often, when you're listening to a piece for the first time, you're listening through a model of other pieces that you know. At a certain point, a piece becomes idiosyncratic and you start to understand it on its own terms.

It's always a thrill for me to see new versions of my pieces on YouTube.

I can't say that there's a common practice that has to do with pitch language or with the way pieces are put together because today, anything is fair game. As far as I'm concerned, my own common practice is a piece that engages the attention of listeners from beginning to end, and doesn't rely on or expect the listener to zone out.

I came up in the '60s; that was a time when there was a revolution going on in music. Stravinsky had become a twelve-tone composer; even Aaron Copland was writing twelve-tone pieces at that time!

I came to what I think of as the critical problem: the aging process of a piece of music. I noticed in the '70s that pieces I wrote would sound great the first time I listened to them and then on repeated hearings they sounded older and older until what seemed exciting and vibrant on first listening became stale.

I think you'll find a significant number of people who decide not to enter competitions because their music just won't fit in that world.
