<p>My son is a music major/composer in his second year at Yale. I also report that the program is excellent, with a lot of opportunities. I think most of the composers have gone to summer composition programs (for my son, it was BUTI), and many of them have been involved in pre-college composition programs at major music schools. I would not submit a composition supplement unless you have some independent review of its quality, preferably by a composition teacher. As for a performance supplement, it sounds like that would make sense for you.</p>
