Dearest Pianoexpert, could you help me understand in simple words how keyboard blocks work? From the figures I have, I notice they have a kind of brass plate with a brass screw; what is that for? How is the keyboard regulated?
Excuse me, also that lever they have at the back... what is it for?
Thank you very much for your clarifications regarding this matter.
Essentially, the keyboard blocks serve to determine the hammer strike point. In the treble notes, it is crucial for a good sound and to avoid breaking the strings. The large screw serves to determine the end of the frame movement when pushing the "una corda" pedal.
