<p>Maybe neither? </p>
<p>At both CMU and RICE, music and math are in different schools. If they don’t have separate admissions (I think they do), each of the music schools will require a level of competence and commitment that would make a double major very close to impossible - IF a student happened to get into both schools.</p>
<p>I can think of plenty of fine places where one could much more easily manage to double math and music makors.</p>
