Give yourself plenty of time to prepare. If you do not have a private instructor, consider finding one for at least a few lessons. Showcase your abilities by choosing repertoire that is neither simplistic nor overly difficult. Know the expectations for the audition. How many pieces should you perform, and in what styles? Should the works be memorized? Will you be asked to sightread? Contact the music department if you are unsure about anything.
A clean, well-groomed appearance is essential. Dress professionally. Men should wear dress pants, shirt and tie. A blazer or suit would also be appropriate. Women should wear dress slacks and blouse or a modest dress. Avoid strong perfume or cologne. Ladies, keep your makeup moderate. Make sure your clothing is reasonably comfortable and doesn't restrict your movement or breathing.
Arrive at the audition site early to allow time to warm up. Unfamiliar college campuses can be tricky to navigate, so scope out the location ahead of time if possible to reduce the stress of finding it on the day of the audition. Keep contact numbers with you in case you need to call the music department for any reason.
Speak in a friendly manner but don't be too informal or familiar. Smile and make eye contact. Faculty members with a doctorate degree should be addressed as "Doctor," while those with a master's degree should be addressed as "Professor." If possible, gather this information ahead of time from their faculty profiles online.
Before the performance, breathe deeply and relax. If you make a mistake during the performance, don't comment on it or apologize for it. Keep cool and continue on. If the professors want to give you advice or work with you on your piece, don't argue with them. Graciously accept their feedback and implement it immediately. Remember, they are looking for teachability.
A short interview might be a part of your audition. Think about your answers to some common questions ahead of time. What are your career goals? Why would you like to be a music major at this college? Have a couple of questions ready in case you are given an opportunity to ask some. You might ask about music ensembles or cultural opportunities available on the campus and in the community.
