<p>Your numbers are on the lowish end for USC, but for Thornton, your audition will account for 90% of the admission decision.
That's true for piano, anyway-- I don't really know how decisions are made for the music business program.</p>
<p>Honestly...it is not possible to predict chances for music programs that require an audition. There variables are...the caliber of all those who audition, the number of students auditioning, YOUR specific audition, and the needs of the school re: instrumentation. If you are one of the top students auditioning, you play your "A" audition and not too many others do better than you, and the school needs someone who plays your instrument, you'll likely get accepted.</p>
