<p>Welcome to CC, heleta.</p>
<p>That's a tall order for four years. Are both you and he willing to consider an additional semester or two to fit all of that in? There are a lot of schools that have composition, piano and violin programs, plus chamber ensembles and entire other fields of study. The problem is going to be that there are limits on the number of classes per semester that he can take, as well as on the hours in the day available for classes, rehearsals, practice on two very different instruments and homework, let alone things like eating, sleeping and so forth.</p>
<p>I would suggest you start by trying to find schools that have both a piano teacher and a composition teacher that your son can work with. For music students, it is really more about the relationship with the teacher than it is about the name on the school. It is a good idea to take sample lessons with teachers at several different schools to get an idea of which appear to be a good fit and which do not.</p>
<p>Of the schools you mention, Yale does not have an undergraduate BM program, but they do have a BA program and some excellent ensembles. That may work well with his desire to take non-musical classes, but I do not know if it would give him enough time on music to cover composition, piano and violin. Yale School of Music is a graduate school and it is rare that undergrads get to study with the applied teachers there.</p>
<p>Michigan and USC are well-regarded both for their music programs and their academics as a whole. If he wants a large institution, both would be excellent possibilities to investigate. Some other large schools with very good music departments include Arizona, Arizona State, Boston University, DePaul, Illinois (Urbana-Champaign), Indiana University, Michigan State, Northwestern, Texas (Austin) and Wisconsin. (That's off the top of my head and there are certainly some great ones I have left out.)</p>
<p>There are also some smaller schools that might satisfy both his musical and other intellectual interests, including places like Bard, DePauw, Lawrence, Oberlin, Rice and St. Olaf.</p>
<p>If you are unfamiliar with the whole process of checking out teachers and schools, might I (immodestly) point you to my series of postings at <a href="http://talk.collegeconfidential.com/music-major/258796-so-you-want-music-major-one-family-s-experience.html%5B/url%5D">http://talk.collegeconfidential.com/music-major/258796-so-you-want-music-major-one-family-s-experience.html</a></p>
<p>Good luck, and I hope others will chime in with some more suggestions for you.</p>
