Since I often receive questions about the difference between harpsichord and piano, I made models of actions of Christofori's Piano e Forte and harpsichord. I used a 1.0 mm OD cantilever with a small Japanese style bell at the end in place of a string. By this arrangement, it is possible to recognize how piano and forte sound is made by the Cristofori's action, while the harpsichord action can hardly change the sound level.
