Just today I had to tune a nice Hamburg "B" for a CBC recording. I was to tune the piano in the mid morning and touch up after rehearsal. The piano has a 2 tank DC and a full length cover. The cover was on before I tuned it this morning. The pitch was about 1 cent sharp. When I came back this afternoon, the stage lights were on and the temperature had raised about to 85 Farenheit so I suspect the humidity level had gone down also since the piano was open. The tuning I had done in the morning was GONE. The unisons sounded out of focus (some of them bad) and the pitch had gone down -2 cents. The stage manager came and told me he had to turn on the air conditionner... At that point, I was half way done. Well, the pitch came back up to + 2 cents and the temperament section went out slightly (just enough for me to start all over). So, I don't know if it's the temperature or the humidity, but stage conditions can really upset me. It was now 6:30 and I was getting tired. I was also getting upset because I was kind of chasing a shadow... So, after all, I wasn't pleased with my tuning (sounded not so bad, but not as good as this morning). Feels good to be able to talk about it. Marcel Carey, RPT Sherbrooke, QC
