Joseph Kerman and Gary Tomlinson are leading musicologists and music educators. Kerman, Professor Emeritus at the University of California at Berkeley, served two terms as Chair of the Music Department, and Tomlinson has done the same at the University of Pennsylvania. Both are known as inspirational and wide-ranging teachers; between them, their course offerings encompass harmony and ear training, opera, world music, interdisciplinary studies, seminars in music history and criticism, and—many times—Introduction to Music for nonmajor students.
