Piano keys, the fundamental components of any piano, can face wear and tear over time. Whether it’s due to frequent use, accidental damage, or environmental factors, piano keys may require repair or replacement. As a piano enthusiast or a professional musician, encountering damaged piano keys can be disheartening. However, the good news is that many issues with piano keys can indeed be fixed.

Common Issues with Piano Keys
