At the previous musicale, I just noticed we were talking two different things:
Stage Fright: the anxiety, fear, or persistent phobia which may be aroused in an individual by the requirement to perform in front of an audience.
Stage Flight : On stage when you loose control, you tend to speed up, which equals Flight: handing control over to behavioral functions and letting your legs and your hands run you out of the problem zone. ( This is my problem....)
Fight: You have to face the realty of the situation and Fight. That means bravely brace yourself and listen to and take responsibility for every note, even if it's scary, perhaps slowing down. Give your musical brain a chance
My previous teacher, Dr. Jura Margulis, wrote a wonderful book "Pianist to Pianist".
