Remember that they are reviewing other candidates under the same conditions and taking notes on everything you say and do. Choosing a program that will appeal to a committee of non-percussionists, demonstrate your versatility, and be performed on unfamiliar instruments is a real challenge. Showcase your strengths and your experience in this short performance. A well organized folder with a printed program including title, composer, and dates along with copies of your teaching exercises and materials you might use in the master class is a nice touch. This will help the committee to understand your teaching methods.
Organization is extremely important in the academic environment.
The committee is not only looking for a teacher to inspire students musically, but to run the percussion department efficiently. Perhaps the most important part of the interview is to convey your philosophy of percussion education to the committee. Not every teacher and school are a good match. When auditioning fresh out of school with little or no teaching experience, your willingness to adapt and teach as the school directs, will be impressive to the committee. I must be a failure.
