What Makes Your Music “American”?

What is “American” classical music? For one thing, I suppose you had to be born in America to write it? Well, what if you were born in another country, moved here and became an American? O.K., let’s say you were born in the U.S. What makes your music distinctly “American”? Perhaps, the lines are so blurred that it isn’t possible to tell anymore. Someone said to me that Europeans try to write jazz elements into their music but they don’t do it well because they weren’t born here. Most of us have listened to and studied European composers and theory as part of our education to become composers/musicians. Is there a way to sort out what is American from what isn’t? Is the world of today’s classical music becoming homogenized?
