Regulationin piano care refers to the precise adjustment of the action mechanism—the thousands of moving parts (keys, hammers, dampers, levers, springs, felts) that connect your fingers to the strings. Over time, wear, compression of felt, and changes in humidity cause these parts to drift out of alignment. Regulation restores them to their proper settings.
Here’s how it affects your piano:
Benefits of Proper Regulation
-
Improved Touch & Responsiveness
-
Keys feel even and consistent across the keyboard.
-
Eliminates sluggish or uneven keys.

Makes the piano easier to control, especially for beginners and advanced players alike.

Expands expressive range—your piano responds more faithfully to your musical intentions.
-
-
Faster Note Repetition
-
Essential for advanced repertoire (e.g., trills, repeated notes, fast passages).

A well-regulated action allows hammers to reset quickly for clean, precise repetition.
-
-
Balanced Tone Production
-
Ensures hammers strike the strings at the correct angle and with the right force.
-
Produces a cleaner, more powerful, and even tone across registers.
-

Extended Lifespan of Parts
-
Prevents uneven wear on hammers, felts, and keys.

Reduces stress on the action, helping the piano last longer.
-
