Pianos are mainly made of wood, and even though most modern pianos are made with more effective wood drying techniques, the wood will still change with the temperature and humidity. Therefore, it is very important to maintain the relative stability of indoor temperature and humidity. Especially in the north of China, the winter is very dry, indoors put a pot of water is the most simple and effective way to prevent the wood from drying and deformation. In addition, don't get too close to the heater.
Unlike stringed instruments which only need to achieve “relative accuracy”, piano tuning must achieve “absolute accuracy” and “pitch stability”. Therefore, intonation is the most basic requirement. At the beginning of the work, the piano technician will first open the piano, use the special tuning wrench and tuning fork, start from the base note to adjust the pitch, spend more than an hour to adjust the pitch. This is just the beginning.
