<p>Note that several of the schools you mention do not have a major in music performance. While you may be able to do some performance/lessons for credit, most of the major will be music history, theory, etc. You also may find that at a couple of them the only music major is a B.M. in the music school, which you may or may not want.
I would add that your list is pretty lopsided. It’s not that you have too many reaches, but that you don’t have enough matches. There seems to me to be too much of a gap between Vanderbilt and Northwestern (which asre still reaches, although a bit less than the Ivies and Stanford), and UofW and BYU. I wouldn’t advise anybody to reduce the number of reaches, especially when your shot of getting into any particular one is iffy. Of course, if you really like one of those safeties, or think you’ll get a nice scholarship there, this strategy may make sense.</p>
