Oberlin with TIMARA as one branch of her program might be interesting. They also have a BA in Musical Studies program that gives access to the conservatory resources, and double degrees are very common there.
Is she submitting a music supplement, if accepted by the schools? That can often help with admissions.
SUNY Purchase would be a good possibility too.
About the Program • Mathematics/Computer Science • Purchase College BA may not be what she wants but the composing and studio/production programs are excellent.
