What is the best temperature and humidity for my piano?
Manufacturers like to say that the temperature should be at 72 degrees F. and the humidity about 45 percent. However, given climatic realities, human needs, and energy conservation issues, this may not always be possible or practical. In truth, pianos are not so delicate that they require such precision in their environment. Any temperature and humidity that are not extreme and are relatively constant will do. The more consistent the better.
