About piano tuning

The principle of piano tuning is: use a professional tool (wrench) to turn the string shaft and adjust the pitch through the tightness of the string (the pitch will be low if the string is loose, and it will be high if the string is tight). 2. How often should the piano be tuned at home? Generally, domestic pianos are tuned once every six months to one year, and the specific tuning time depends on the quality of the piano itself and the frequency of using the piano. 3. Does the piano need to be tuned after moving or moving? Strictly speaking, the piano needs to be tuned when moving, because the piano after moving will have small errors in pitch and other feel. If the pitch is not too high, there is no need to debug!
