Over the months and years, as the piano is played, the felt and leather of the action pieces will compress and harden, causing the parts to drift out of alignment, and creating excess action noise. Each of these parts rotates on tiny metal hinge-pins housed in delicate cloth bushings, or slide against one another as the key is played. Each system of levers is comprised of a variety of small parts made of wood, leather, and felt. What causes the action regulation to deteriorate, and what processes are involved in restoring the regulation?Īs with any machine, the piano action’s efficiency declines with age and use. The goal, then, of piano regulation is to maximize the player’s control of the piano’s range of musical expression by means of mechanical adjustments to each of these systems of levers. This hammer speed, in turn, directly affects both the volume of the piano ( quantity of sound) and, to some extent, the tonal characteristics ( quality of sound) of the piano. Each of these machines – one per note – is itself a system of levers which controls the speed of a felt-covered hammer as it strikes the string. The piano’s action is a collection of 88 separate machines all of which are attached to, or directly resting on, a single frame which slides into the action cavity in the front of the piano. What, exactly, is the piano’s action, and how does it work? Reduce the long-range cost of action maintenance.Prolong the useful life of the action parts.Reduction of wear and tear on individual parts, which will:.Control over piano’s dynamic range and corresponding tonal quality.Enhanced control over the piano’s range of musical expression by maximizing:.What are the benefits of routine action regulation? The best way to understand the need for, and benefits of routine action regulation is to become acquainted with a few of the basics of what the action is, and how it functions. Understandably, this awareness usually creates more questions than answers in the customer’s mind. ![]() ![]() Most piano owners, at some point, become aware (either by noticing that their piano is becoming more difficult to play or by having that fact brought to their attention by a technician) that their piano is in need of mechanical adjustments to the action – a process referred to as “action regulation”.
