Grad school after Music Technology BM?

I’m currently a junior in high school - just have a quick question regarding what my options would be if I wanted to continue my education after a BM in Music Technology at USC? Since they don’t offer anything higher, where could I take the BM if I decided to get my masters or doctorate? Could I pursue a masters/PhD in history? musicology? English? film school? Just curious if anything like that is possible. I apologize if this is an obvious question - I’ve received conflicting information.
