With regards to playing the piano, I stayed remarkably calm the day before, though I kept waking during the night playing the notes and fingerings in my head. On the day I rehearsed the music about 2 hours before the performance and still stayed fairly calm. The nerves really started about 10 minutes before I was due to start, but I managed to get control over them, enough to play without freaking out. So thank you for your help, I felt that I enjoyed the performance and didn’t make any huge mistakes. My husband tells me he has never known me this calm in the run up to a performance.
