A piano brings a lifetime of enjoyment to you and your family. As
you might expect with any investment of this size, a piano requires
period servicing to provide outstanding performance year after year.
When you look inside your piano, you'll discover an intricate system of levers, springs, and hammers connected to the keyboard.
The complex system which causes a hammer to strike a string when you
press a key is called the piano's action. This mechanism needs to be
responsive to every nuance of the pianist's touch.
When a piano leaves the factory, each of its parts is adjusted to a
tolerance of a few thousands of an inch. This process is called action
regulation. Because the wood and felt parts of the action may change
their dimensions due to the humidity and wear, the action must be
serviced occasionally to maintain its responsive qualities.
