The biography of Joel Treybig, associate professor of music, was chosen for inclusion in “Trumpet Greats: A Biographical Dictionary.” The biographies in the book were selected by David Hickman at Arizona State University and content editors Edward Tarr, of Germany, and Michel LaPlace, of France. The recently-published text is the largest book ever written about the trumpet: a 1,128-page work featuring biographies of trumpeters and instrument designers from 64 countries who have made important contributions to the profession since 1542.
