Admission question or Thornton School of Music Students

New member to CC. My question is how heavily does USC rely on grades and test results for talented potential Thornton students? Currently, I am a Junior in H.S., and I play the piano, and am the pianist for my H.S. Varsity Jazz band (which is nationally recognized). Also, I am the pianist for a Caleb Chapman band (also Nationally recognized) that will be touring the U.K. this summer. My grades in H.S. are pretty good (3.5 unweighted), and I have ACT scores of 30 in math, 30 in english, 29 in science and 25 in reading. How important are grades as opposed to say my musical talent, audition, tape, etc.?

Grades, scores, essay and honors are all considered. For Thornton the audition is of major importance. Some of the professors may only take two or three students a year. Your ability and performance should be at a high level.

On the Thornton website it is possible to listen to selected music recordings. This may give you an idea of the level expected.

Only submit your best ACT or SAT score.
