The action is the direct intermediary between the pianist and the strings and is comprised of many complicated levers of various classes, starting with the keystick and ending with the hammer. Rebuilding and designing an action is a poetic dance of geometry and weight.


The player must have the ability to control the dynamics and velocity of each note and clusters of notes. Of particular importance is the hammer which must have an appropriate mass and resiliency to excite the potential range of available sound contained in the string scale and soundboard assembly. This is why we are strong proponents of hammer sampling, where-by various makes of hammers are auditioned only once the piano has been strung with its new belly.
