This question is mainly geared towards those taking performance at a college/conservatory/university, but anyone can answer. What do you do when you have to perform for a hostile audience? How do you mentally prepare for that? What I mean is other teachers on the jury who you may not get along with, peers that are comparing your playing to theirs and judging you, and/or people who just plain don't like you very much (but pretend too!). I've heard some horror stories about such things and I am entering that world myself next year. My plan is to keep my head down and stay out of trouble, but I'm the type of person that won't stay silent if I see someone doing something wrong (gets me in alot of trouble sometimes). Anyways, I thought it might be an interesting discussion. And if any of you have been in such a situation (doesn't even necessarily need to be at one of the listed institutions), please share what you did.
Frankly we are being judged by everybody, all the time. This is just life. As far as peers judging us, we have to have enough confidence in what we do that their judgment will seem less and less important; you have to be better than your peers.
Rosenthal relates an anecdote about Brahms; they were having a coffee in Vienna with another professor from the Conservatory, who had to leave to teach. He had "the effrontery to say to Brahms, 'What a nice life you have! If only I could enjoy my coffee in the afternoon.'" Brahms replied, "Let me tell you something. Work hard, impress your colleagues, and then you too can enjoy your coffee."
In the end, impressing an audience is nothing compared to impressing your peers. Mozart too, cared the most when playing for the educated, who were appropriately amazed, and for the right reasons.
I don't actually believe that judges are as "hostile" as many seem to think they are all the time. I suspect that many young pianists expect a certain reaction to their playing, and when they don't get it, they imagine the listener to be hostile.
