<p>In your situation, I would still want to get to know the composition teachers at each of the schools you are considering. Even if you do not know which of them you like at present, you may well find that there are some whose works do nothing for you at all. Also make sure to check out the curriculum. Some places may not give you access to the top composition faculty until you have taken a bunch of prerequisites in your first year or two. I sense that you want to get cracking on composition from day 1.</p>
<p>Although WindCloudUltra points out that Princeton’s grad program is stronger than their undergrad, Paul Lansky, Steven Mackey and Barbara White have put together an interesting set of courses that integrate composition into the undergrad music theory sequence. While not a Princeton grad myself, I have occasionally performed with some of their ensembles and have always been favorably impressed by their faculty and students. I really think it is worth a look in your case.</p>
