<p>Wow! I’m just in awe of your accomplishments. You have an excellent chance of getting in almost anywhere, and you’ve included some realistic match schools on your list, as well. Carnegie-Mellon is renowned not only for science, but for its Musical Theater program, and so you might consider applying there for Math & IR (I’m not sure about their IR), and see if you could get involved with music along the way, also. Vanderbilt also has great music, along with strong academic programs. Don’t overlook MIT, either. They are best known for STEM, but their Social Sciences are first-rate. Philadelphia is also a wonderful city for music, and so you should look at Penn.</p>
