Big seasonal (or weekly) humidity swings are a major accelerator to aging, and stability is much more important than the absolute number. > Another question : Do many agree that a small external humidifier near > the piano will help significantly in adding some humidity to every part > of the piano when needed (soundboard and pinblock and action, in a grand > piano), albeit as a second choice to whole room conditioning ? It depends on the heating system. With something like room contained convection or radiant heating, an auxiliary humidifier will, or can, help. With a forced air system whatever humidity you put into any given room is sucked out and distributed throughout the house. So unless your humidifier in building wide a forced air system is going through eight gallons or so a day, it's probably not going to help much. Ron N
