The articles are assembled to form a piano action with significantly less dynamic mass which is much more responsive to the touch. In addition, the new action provides the valuable collateral benefits of increased efficiency of manufacture and maintenance. The invention also provides the capability to achieve true half stroke design in both the sharp and white keys. Additionally, the application discloses a universal composite grand piano action that is capable of being installed into any brand of grand piano.</p>
