I’m not sure Harvard will be in the cards for you. Your unweighted GPA is comparatively low to other Ivy League applicants with a perfect 4.0. Also, your EC’s aren’t that strong. I understand that music probably takes up a lot of your time, but you should try to get involved in some other stuff. In addition, try to get some leadership positions because I’m not seeing any now.
You seem like a great applicant, but you’ll be up against the most qualified applicants from all over the world. It’s hard to predict anything without more scores, so don’t give up hope if Harvard is where you really want to go.
