I am getting ready for an audition, and, yes, because I had a banana before a previous successful audition, I am making this part of my preparation, as well as deep breathing, relaxation CDs, etc., visualizing a positive outcome, etc. All of these will be helpful on the day of the audition, but, even after reading many of the books on performance anxiety and trying the exercises, I just do not think there is anything more helpful than really learning the material and being prepared. Lack of preparation = anxiety for me
A question I am asking myself is.. am I practicing effectively. Of all the books I have read on the topic of performance anxiety, and they all had something to offer, the one that stands out is a book about the topic of practicing called "Practicing for Artistic Success, The Musicians' Guide to Sel-Empowerment" by Burton Kaplan. This book is amazing and has helped me to practice more effectivity, challenge my thinking, and much, much more. I have really only skimmed the surface so far. He identifies many of the problems with stage fright to inconsistency or inadequacy in the practice process.
My goal for my audition is to do everything possible to enhance my mental and physical health on the day of the audition. There will be a banana and deep breathing, but I also want to be walking in there knowing that I am prepared and really know the material.
