Also, take a look at Bard. Of note, they require all conservatory students to double degree (5 year program). This was a primary factor that drew my daughter there. High quality conservatory education + understanding faculty with significant experience balancing the 2 degrees. The liberal arts education has also been a great fit for our daughter. It’s very truly a lot of work, but if the double degree/major is what your daughter is seeking, it’s really nice to be somewhere that encourages it, not just tolerates it.
Financial Aid-wise, Bard College is meets need school, but the conservatory provides very generous merit scholarships. You can also potentially get $$ from both the college and conservatory. And if it’s your first choice, but the first FA offer doesn’t make it accessible, ask for more $$.
Your daughter sounds like she is at a level that would be competitive to be accepted at Bard as a violist.
