One thing to think about – students I’ve known at Haverford have chosen to participate in ensembles in Philadelphia not affiliated with the school. The two who come to mind were both somewhat exceptional but didn’t want to go the conservatory route. This is definitely another way to think about this.
Ditto for students in the Boston area, although they were all jazz musicians.
Your D should think about what she wants her music experience to be. Is it a way to connect with other students at college? Does she want top instruction and to perform at the highest level possible? Or just enjoyment? Really, most high selective LACs will have decent outlets for talented musicians. But if she’s looking for greater intensity, she may find that by attending school where those opportunities abound.
Bard is another to look at, btw.
