Systems, methods, and devices for improving the mechanisms of musical instruments, including
piano and similar instruments, through the integration of compliant mechanisms, improved or better selected materials, and improved or better selected manufacturing processes. A device may include a
damper underlever. The
damper underlever may include a plurality of rigid links. The rigid links may include a
damper flange, a damper lever connected to the damper
flange by a first rotational connection, and a damper block connected to the damper lever by a second rotational connection. The damper underlever may also include a first compliant feature providing rotational motion between at least two rigid links.
