Berklee College of Music is a great school for composition. They're mostly a "popular genre" school, but to get into classical through them, they have a partnership with Boston University. That's what I was told by the School reps. during my audition, when I asked. I ended up attending Academy of Art University, but their focus is for Visual Media (Video Games, Movies & Television)....Not so much of "traditional" music for Band and Orchestra. Its Music Production & Sound Design for Visual Media. Not sure about their masters program, but I know for sure it has the same name for the major. I know of many Performance schools that are great....not many Composition ones.......
