I need help finding a place where I could take music classes at, classes for guitar on subjects like music theory... I've tried to google a few different things but I cant seem to find a place or even a phone number which I could call to find out some info.

My mom suggested I search colleges which provide classes but I have no idea which colleges would have music classes (except berklee).

So, does anyone know what I can search for to help me find music classes or know any place around where I am located.

I live in New Jersey and can travel easily to New York...

Thank You!
Your local community college should have some. Go there and ask for a catalog of courses, and then go and talk to your counselor (that is if you are in highschool) and see what you need to do to get into the college.
