Piano Regulation

Piano regulating is a matter of making numerous adjustments to the pianos action (its moving parts) to optimize the performance and tonal quality of the instrument. These adjustments start from the key right through to the hammer as each place where action parts are in contact with each other wears. The piano action is known as a “train of levers” because of the multiple points of contact throughout the action. These adjustments are minute but additive to each other making a large difference to the player after a regulation is done. Each felt or cloth compresses, the wooden parts have possibly shifted or swollen, or have shrunk. All of these variables together make a difference in the overall playing and sound of your instrument.

The two most important things in considering an instrument is how it plays and how it sounds. after some years of having your piano it is more than likely that the feel and the sound of your piano has changed and a regulation is a great way to bring back the glory of your instrument since its original purchase.


When the piano was manufactured and delivered to the dealer, the piano was initially regulated (setup) to very exact specifications. This allows the piano’s action to play or repeat as fast as possible and also have as broad a dynamic range as possible. The ability to play very fast and very quietly or very loud, with even continuity and uniformity across the entire keyboard is a sign of a well-regulated instrument.

As a piano ages and especially under normal to heavy use it begins to wear and becomes sluggish and inconsistent in its playing and tonal qualities. The player rarely notices the difference because of our ability to adapt. things like regulation and tuning slip gradually and we don’t notice the actual change that happens. This is horrible in the aspect of tuning because we are training our ear to the piano we play and the sounds we hear, however out of tune become normal. The same happens with our playing and we only notice a difference when we play an instrument that is well regulated and maintained to compare ours to. A piano, both the action and case are made mostly of wood, felt and buckskin, these materials begin to wear and compress and require the need for adjustment. While moderate wear can be dealt with through making actual adjustments to the action, severe wear as seen on older instruments usually requires replacing felt or leather in which case the action would need to be overhauled or reconditioned and then regulated.
