Piano adjusting mechanism - is actuated by component moved by bending player's body

摘要

The grand piano has a mechanism (9) affecting the sound generated by the keys. This is actuated by a component (3) mounted centrally in front of the keyboard(2), and roughly at the player's chest height, so as to be moved by bending the body forwards and rearwards. This can be coupled to the mechanism by a thrust rod sliding axially(4), and which is adjustable for length. ADVANTAGE - No disturbing effect on player.
