What is Action Regulation and does my piano need it?
“Action Regulation” simply refers to the adjustments that a piano needs to make all the moving parts move the right way. The piano is a very simple, yet very technical instrument. From the key to the hammer that strikes the strings, there are levers and such that move in a very precise way to make the note play correctly. Each note on a vertical upright has 25 or more adjustments that can be made, and a grand has nearly 35. If any of these are incorrect, it will affect how the instrument performs.
