Music Minor?

I am a senior in high school applying as a physical therapy major to Northeastern early action this fall. I know the program leaves courses for a minor, and ideally I would like to be a music performance minor however I see there is an audition requirement. The audition wouldn’t be a problem, but I was just wondering if it was to be done during application season or only if you are accepted and attend. I emailed the person in charge of them but haven’t heard back, can anyone help me out?
