Piano Regulation

The Piano Action, the system of keys, levers and hammers, that links a player’s fingers to the strings of the piano is the engine that drives the instrument. Developed through centuries of experimentation and innovation, the piano action’s job is to transfer a player’s manipulation of the keys through a system of levers to effect how the hammers strike the strings. From thunderous chords to the softest melody a well-regulated action is the ultimate “touch-sensitive” system allowing a player to produce a full range of expression.

Over time and use, felts compress, parts wear, and the action works less and less efficiently. Regulation is a series of adjustments made to the action to re-establish its proper balance and responsiveness. These adjustments can be minor – taking an hour or two to complete in the home. Or they can require a complete overhaul of the action including replacement of most of the action parts.
