> adding some humidity to every part of the piano when needed ..... Maybe every humidity to some parts in an uncontrolled manner. I suppose in maybe an extreme condition it might be better than nothing. Whole room is best. A proper Damp Chaser installation with the humidity kit and a back/bottom cover is a very good second choice. I'd rate a small external humidifier near the piano as a VERY distant ninth choice. If not whole room, why not just get a good DC unit?
