I had 7:30 chemistry.

You'll probably take general classes and then your music classes. I don't know much about the structure of music majors at my college let alone where you're going, but you'll probably have one class that is technique, and then more that is like practical as a drill or lab.

Then general math, history/economics, english, and a science.

You'll probably take something like cal I, antropology/government, chemistry, whatever music classes you have and possibly a foriegn language or second 'easy science' or Humanities.
