It is that time of year again that many college students dread: juries. Many music majors get very worked up about playing their instruments for just 10 or 15 minutes in front of the faculty. Here is a great article that I found via John Manning's blog titled 'What Every Musician Ought to Know About Stage Fright'. This is a fantastic article from a great website. The article goes into why we experience stage fright and offers up some ideas on what will and what won't help to combat it.
The best way to get over stage fright is experience performing but this article offers up some very helpful tips in the meantime.
