Black Suits, you are welcome! When we started out on our BFA MT adventure, quite frankly I had no idea about the magnitude of NYU Tisch's program either, and it actually took me quite some time to disect all my D's notes. With a little additional help from the Tisch website and CC (SoozieVT

) however, I was able to "get my hands around things" somewhat.
As NMR already mentioned, when you complete you information sheet the day of your audition, you can specify what studio(s) you want to be considered for. However, the adjudicators may have a different point of view and, if you indicated that you simply wanted to be considered for any of Tisch's drama studios, they may place you where they feel you would fit best. Also, when you schedule your audition, you can actually sign up for "drama" or "musical theatre" slots, although I get the impression that there is a lot of crossover, as all dates in fact accommodate both types of audition.
Among the many things that attracted my D to NYU was that Tisch's program, and CAP21 in particular, is larger in size (more people to meet, learn with & from) and the many different directions (advanced studios) to chose from; also the attention one gets, is still very personal as if in a small program as the classes are typically 15 people max.
