Bach is considered by many to be “the father of the development of clavichord playing.” He composed numerous works for the instrument and, therefore, had a significant influence both on clavichord playing and clavichord building in Germany.
I’ve read that Bach had a certain “touch” on the keyboard, be it on the clavichord, the harpsichord or the organ. That “touch” is of huge importance in clavichord technique. In fact, many Bach scholars believe that the clavichord was Bach’s favorite keyboard instrument!
