Performing feels uncomfortable. Sometimes horribly so. Accept that as a truth and go so far as to lean into your stage fright.
The fear you are feeling signals that you are considering a project that is meaningful and important to your growth as a musician and human being. So acknowledge that being on stage is different than every day life; it’s not like tying your shoes or waxing your car.
Expect the inevitable butterflies, shaky knees and sweaty palms. The worst thing you can do is to try and push away these physical manifestations of how you’re feeling. Instead, go further by looking forward and getting inside these symptoms. Act as a neutral outside observer as the internal/external storm comes and goes. Watch it pass; it always does.
Here’s your transformation: The violin teaches you to release the fear and ignore the transient voices that hold you back. It is a shining, positive force for every part of your personal growth.
