The influence of humidity on piano

①Major components of a piano such as the case, strung back assembly, action, keyboard and so on are made out of material like timber, felt,worsted,leather and metal, etc, which are especilly sensitive to humidity, so the piano room should keep a relative humidity of 40%-70%.

②When it is too moist or rainy, confirm that the windows and doors of the piano room are closed; after playing, close the top as well as the fallboard in time. Put some desiccant inside and change it regularly to keep the components from deforming or rusting. It is better to put the piano in a room with modest temperature.

③When it is too dry, put a basin with water in the room. With the water's spontaneous evaperation, the room will be not too dry and the components won't become deformed or alligatored caused by dry condition.
