How to make the most of D's marching band involvement if she won't be music major

My D1 has been playing the cello since she was 4, and became very accomplished, winning numerous competitions etc. She is not a music major but did get a talent based scholarship and plays in the university’s philharmonic where all the music majors play.

As an aside, she got a very good internship for this summer in a STEM field, and her interviewers later told her that one of the reasons they hired her was because she was a musician, and has the ability to see patterns clearly.
