I`m wondering if anyone has played or even heard of Concerto for Band by Leonard Duarte, although I doubt if many people have....he`s a local composer and a friend of our band director, but he was band director before our current one at my high school. Anyway, that`s the audition piece for chairs this year and I was wondering if anyone has played it and has any advice.

why don`t you ask the composer? You can email himn and ask a question from his site www.duartemusic.com
