If you are not opposed to the Midwest then two potential optional are:
- Illinois Tech in Chicago. They have a strong CS program and partnership with Vandercook School of Music. My daughter is currently attending Illinois Tech and has quite a few friend that take music classes at Vandercook. Vendercook has a building on Illinois Tech’s campus.
- Rose-Hulman in Terra Haute, IN. Rose does embrace the arts and has very active band, orchestra, and dance groups that perform on campus.
Both a small STEM schools with good CS programs and decent access to music training and performances.
