Abstract

A piano selectively playable in normal and soft modes has multiple piano keys and actions, including a wippen assembly, and multiple piano hammers. A soft pedal system includes a soft pedal and a hammer rest rail mounted for movement between normal and soft mode positions. A piano key lift rail is mounted for movement between a normal mode position spaced from lifting contact with the keys and a soft mode position in contact with and lifting the keys and the wippen assemblies. A soft pedal linkage assembly between the soft pedal and the hammer rest rail and piano key lift rail, upon actuation of the soft pedal, causes movement of hammer rest rail and piano hammers, and movement of the piano keys and the wippen assemblies, between normal and soft mode positions, in gap-closing motion.
