@engineer,

MIT has an excellent music program. I know a few faculty and students there and my impression is that it is particularly good for composition.
The nice thing about the Boston area in general is that there is a lot of interaction between schools. I know MIT musicians who take classes and perform at NEC, Harvard, etc., and vice versa. Boston in general (along with New York, San Francisco, and other big artsy cities) is the kind of place where there's enough musical activity going on that you could easily be involved with music without actually having to major in it. (I'm told Pittsburgh has a growing musical scene for classical music as well, with Carnegie Mellon and U. of Pittsburgh having lots of musical opportunities.)
If it's performance rather than composition that is more your son's calling, then many of the big universities already mentioned are good candidates. If your son plays violin, it might be a good idea to aim for a bigger school that has a decently sized orchestra, since orchestral music is as crucial (and for some violinists even more crucial) to the instrument as solo or chamber repertoire. This is not to say you can't find a good orchestra at a small school, but small schools sometimes have trouble maintaining a large ensemble of consistent quality from year to year owing to the smaller population of students to choose from. This was the case at my own undergraduate alma mater, and my current school--also of the small liberal arts variety--has a student population of just under 1500; we've never had a full-time orchestra because there just aren't enough musically inclined students to sustain one from year to year.
