Piano restoration is the process of repairing and refurbishing an old or damaged piano to bring it back to its original condition or improve its playability. This can involve fixing or replacing worn-out parts, such as strings, hammers, and action mechanisms, as well as refinishing the exterior to restore its appearance. The restoration process often requires skilled craftsmen, known as piano technicians, who have expertise in both the mechanical and aesthetic aspects of pianos. They assess the instrument's condition and determine the necessary repairs, ensuring that the piano not only looks beautiful but also sounds its best.
