Abstract:
1. A method for coupling each of a plurality of strings with a sound bridge of a piano, wherein the piano includes a plurality of tuning pins and a plurality of hitch pins, each string being coupled to one of the plurality of hitch pins and to one of the plurality of tuning pins, and extending therebetween, and wherein the piano includes a sound board coupled to the sound bridge, the method comprising: imparting one or more substantially steady state first forces to the string at one or more first locations along the string between the hitch pin and the tuning pin of the string, the one or more first forces having magnitudes of force and directions of force summing to a first magnitude of force with a first direction of force being substantially away from the sound bridge causing the string to impart one or more substantially steady state second forces having magnitudes of force and directions of force summing to a second magnitude of force substantially equal to the first magnitude of force with a second direction of force substantially opposite the first direction of force and being substantially toward the sound bridge; conducting the one or more second forces to substantially impart the second magnitude of force to the sound bridge in the second direction of force; imparting one or more substantially steady state third forces to the string at one or more third locations along the string between the hitch pin and the tuning pin of the string, the one or more third forces having magnitudes of force and directions of force summing to a third magnitude of force being substantially equal to the first magnitude of force with a third direction of force being substantially opposite the first direction of force and substantially toward the sound bridge causing the string to impart one or more substantially steady state fourth forces having magnitudes of force and directions of force summing to a fourth magnitude of force substantially equal to the first magnitude of force with a fourth direction of force substantially opposite the second direction of force and substantially away from the sound bridge; and conducting the one or more fourth forces to substantially impart the fourth magnitude of force to the sound bridge in the fourth direction of force, the one or more fourth forces substantially compensating the one or more second forces to substantially prevent imparting of the one or more second forces to the sound board.
