Here are some interesting articles and books on how to overcome stage fright (some are music related, some are general):
Performing to Expectations
We're into high performance season for musicians. Some of my students have already begun their stint at the APTA Festival. I was delighted today to see the comments one of my students received. We're definitely on the right track. Just a few tiny things to improve on but nothing this student can't handle. I can only hope that the rest of my students do as well. Some students have recently memorized their exam and/or festival pieces so there may be some wobbly performances. As my brother once told me, "They'll perform as well as expected."
