I have noticed that for years I listen to live music critically and the enjoyment tends to be secondary. I've always thought that I would never want to pay for a performance that I could do better, and when I hear mistakes, that sticks in my mind more so than the enjoyment of the overall performance. I can't help it. I've never performed music that I couldn't play flawlessly, it's why I've shied away from difficult material. The more confident I feel in playing something, the fewer mistakes I make. I can't shake the idea that either most people don't hear the mistakes or don't care. I think a lot depends on the overall quality and sophistication of your playing. Hendrix once said that people copied his mistakes. Miles Davis and John Coltrane basically said that mistakes are opportunities... that works mostly in jazz, because improvisation rules. We have season tickets to our state philharmonic orchestra. If I hear a mistake, it ruins the performance for me when I should be paying more attention to the interpretation of the music and the overall aesthetics. Is anyone else cursed with this?
