Have you ever practiced flawlessly before a musical performance only to screw up at the performance. Well, that happened to me. I was playing Passapeid by Claude Debussy last Saturday and I had a couple of practice runs that were just flawless. The notes were all there and timing was just perfect. I was feeling good — then came the performance. I really don’t know what happened. I played one note a bit too long. I had to stop. I missed two measures. It’s a good thing, there was a break after that. It was just lack of concentration on my part. Well, I played it off as if nothing happened. I talked to several people afterwards, and no one even noticed. If they only knew.
