I would not worry too much at this at this point. After all, it is still only February. I received an acceptance to the University of Wisconsin-Madison on January 21st (the letter was sent out the first day of Spring classes), but I am betting that the reason for the early notification is because I had already met many of the faculty and spoke to them about my work. I have two other friends at my current undergraduate institution who have applied to various musicology programs and still have yet to hear from most. One, I believe, was accepted to UNC-Chapel Hill pending an upcoming interview, and the other was invited to interview at Florida State (no acceptance yet). The person who was accepted to UNC also applied to about 8-10 programs, but as of today, has only heard from UNC.
I have been freaking out too as a result of having to wait for funding; I have told myself that it is not realistic to attend if I have to take out loans. While I have been accepted, nothing is at all finalized. With the current state of the economy (and how it's affecting universities across the country), I would not be at all surprised if the process this year is much slower...schools are still figuring out budgets, and this heavily impacts their timetable and number of acceptances they will offer.
