Forgot to mention that another great option is to apply to excellent CS programs and continue music as an extracurricular. Many schools will provide lessons and give credit for both lessons and certain performance EC’s. You would want to check out the level of musicianship in ensembles. Again, a music supplement can be helpful.
If you go that route, there are instances where you may want to avoid schools with BM programs (conservatory or school of music) if the best teachers and resources go to the BM students. Not always, but worth checking out.
