I majored in music for undergrad and will be attending medical school in the fall. I would see if you can do a non-education music degree if you want to go this route. Music Ed, at least at my school, requires a semester of student teaching your senior year which would interfere greatly with the application process. I did a BA in music which wasn’t a full performance degree and allowed a lot of flexibility in the courses I took and allowed me to have time for pre med courses and ECs plus practicing music. I’m very happy with my decision to pursue music and medicine, but be sure that you love both of them as this path will involve a lot of long days splitting your time between practicing, rehearsals, and studying.
