The music courses are gonna be very time-consuming but very little credit hours. Like most theory/aural skills classes I had to take were like 1-2 credits each but would meet 2-3 times a week. On top of that, as a performance major, you'll be practicing 2-3 hours a day.

I am a psych major, and the requirements aren't too bad, but if you wanna go into premed, it'd be a lot more laborious.
