I just saw this and the recent response, might be too late for the OP, but maybe can help someone else. Just based on my son’s experience and the members of his group, there is a big difference between stand alone conservatories and music schools in university setting, sometimes really it isn’t so much about academics but simply being within a university. My son went to a conservatory undergrad (NEC) but for grad school went to Rice University (which I’ll talk about in a bit). He really liked after being in the stand alone conservatory being in a university setting, having a campus hangout and so forth. At a place like Northwestern you take classes with non music students, and that can be huge. Same would hold for USC and the other schools in a university I would guess.
Again, depends on the student. Okay, on to the schools (even if this won’t help the OP), o only talking about the ones that I know of through either my son or people around him, if it isn’t on my list, it is simply I don’t know.
Colburn is a very small school, and they have limited faculty. Obviously it being free makes a big difference (I am still crying, my S got in their undergrad). As such you are with the same small group of people and for some that can be a problem. Likewise, with limited faculty, if the teacher isn’t a match you are kind of out of luck, and that can be a problem given the nature of music teaching. My son knows people who went there, and he said that they all said they tend to be very strict there with the students, it is more like a strict summer camp than a typical college environment (and knowing the person running it, not surprised entirely). It does have gorgeous facilities and with the Disney Hall across the street there also is the influence of the LA Phil as well. With chamber, from what I have heard, because the program is small it is kind of a limited group of people you can play with, and from what I know it isn’t emphasized.
USC I have heard, at least in strings, is grad centric. I have heard mixed things about the strings faculty, even though they have had names there (midori was head of it at one point). Culture wise the music school from what I know is integrated into the broader school, so it feels more college like that way.
My son looked at Oberlin. They have decent faculty and it is a competitive school to get into, so you will be playing with relatively high level students. It is in a rural area so the school town is really it. Oberlin from what I know encourages music students to be part of the broader community, and the vibe is , at least according to my son, on the hippy side of things (to date myself lol).
Bienen is part of Northwestern . There are strong academic requirements, the program itself is also known as one of the golden locations for dual degree kids, and they do have good faculty there. It is not distinct from the rest of the school like some music programs in universities are.
Eastmen from what I know (I don’t have that much experience) is the music school is very supportive of their students and they have good faculty there. It does have Rochester in winter , which like much of upstate NY can be cold and snowy. Eastman is kind of standalone from U of Rochester if I heard right.
One school not on the list (which I know won’t help the OP, but maybe others will see it) is Rice University Shepherd. There are a lot of pluses there, they have good faculty, it is a really pretty campus and if you want to be part of the university the music school feels like that from what i can tell (my son went there grad school , not UG, but a member of his ensemble went there UG). For voice students they built an incredible theater for opera, and I have been told they have great faculty. For instrumental students they are a bit unique IME, they are ensemble oriented, unlike most schools that emphasize solo performing, they put a lot of emphasis into their orchestra and chamber music, and if you are thinking of heading that way , it may be a good stepping stone into getting into that world. They have chamber music faculty that are first rate as well. From what I have been told Rice is pretty good with aid as well, both merit and need based.
Again folks these are my impressions, nothing set in stone.
