After years of complaining about the environment in the Music Building at a school that I service, there finally seems to be some movement towards at least exploring a solution to the problem. I have been asked to provide a range of both humidity and temperature that would be considered the minimum requirements for the pianos. Right now, humidity swings between 20% and 70%, measured with my radio shack digital thermo/hygrometer, although I have a hard time believing that it doesn't drop lower than that. Temperatures in the heating season frequently reach into the upper 70's, with a few rooms hitting well above 80F on occasion! I have suggested that anything outside the 30% - 60% range is bad for the pianos, with an ideal of mid 40%'s, but I don't know how to answer the temperature question. Any suggestions?
