At a lot of music schools inside universities, if you get into the music school but not the acacemic school you won’t get in, period, they both have to accept you. Some schools will allow you to get admitted academically and if you don’t pass the audition, apply the next year and re-audition, it depends on the school. From friends of my son going to music schools within universities, the U Mich, USC, Vanderbilt, whether they were doing strictly music or dual degree, the word was that they were more wide range in what they would accept academically than they would with a straight academic admit, so while the academic portion of the university decided seperately, as momof2teengirls said, a student applying to the music school can get in with stats that an academic only admit likely would not get in, they make allowances (it could be with a dual degree person they are a lot tighter with academic stats coming in, as well, that part I am not sure of).
For the OP, if you are really concerned about that, you can always ping the various schools admissions department and ask them if your daughter is within reach, they are there to do such things.
