Action Mechanism
The action is an intricate mechanism made from wood, felt, leather and metals. Its function is to take the energy of the key when depressed by the player into vibrations in the strings. In order for the pianist to achieve satisfying results in playing the subtle nuances in music, the action must be in complete synchronization. This requires very close inspection of all action parts and a fine regulation of the mechanism by the technician.
