What should I major in?

I am a senior in high school. I'm pretty smart (30 ACT, 3.82 GPA, ped 6 AP exams) and well rounded. The thing is I don't know what to major in in college next year. I'm good at math and detailed work, but I don't want a really boring job. I've thought about teaching. I also love music. I've played the cello for 9 years and im very good, but probably not on track to be professional level. It's like I'm pretty good at everything, but not amazing. What should I do?
