When I joined Improv, one of the very first things Bryan told us was that we have to be willing to let go of a story. Once it's told, it's history. Forgotten. Over. The end. Move on. You can't live in a story in the past; you have to live in the present, create new stories.
Music is like that.
The performance is over. It doesn't matter how much practice you put in, or how often you replay the episode in your mind; the performance was what it was, and it's over. Move on.
It's strange how hard it is for me to pull all the music out of my folder. Hours of work, weeks of practice, all for one hour of performance.
Am I putting in the practice now for the Big Performance just around the corner?
