I would look at the Little Ivies (an informal grouping of top LAC’s) https://en.wikipedia.org/wiki/Little_Ivies
Many of these have excellent music departments and will even find a teacher.
Another resource is Colleges that Change Lives- a website,national fair, and, originally, a book by Loren Pope.
There is an excellent book entitled “Creative Colleges” that I found useful and is apparently still available online.
For schools that de-emphasize or don’t require test scores, http://fairtest.org/university/optional Many of the most selective schools are on this list, including little Ivies like Tufts, Middlebury, Williams, Amherst, Bowdoin, Bates, Wesleyan etc. Hamilton is of that caliber too.
I know a jazz musician who went to Tufts and majored in sciences but did a lot of gigging and may have intersected with friends in the NEC double degree program there.
As I wrote in your other thread, I am not sure what “pre-law” means, because students can major in anything and go to law school. In fact music majors do well with admissions to professional schools. Does he want to do history, or economics, or something else? Or is he looking for specific law- oriented programs?
Let us know his preferred location, size (it would seem small is the top choice), academic major, and “vibe.”
There are some great schools in all parts of the country so I didn’t mean to focus on the Northeast
And, yes, once again, the Double Degree Dilemma is useful for some- an essay posted up top on this forum.
