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. 种可在正常和柔音模式下选择性地演奏的钢琴具有多个钢琴键和击弦机，包括联动杆组件，以及多个钢琴弦槌。柔音踏板系统包括柔音踏板和安装用于在正常与柔音模式位置之间移动的弦槌背档。钢琴键抬档安装用于在与键提升接触隔开的正常模式位置和处于接触并提升键和联动杆组件的柔音模式位置之间移动。在柔音踏板与弦槌背档和钢琴键抬档之间的柔音踏板联动组件在柔音踏板的致动时导致弦槌背档和钢琴弦槌移动，并且导致钢琴键和联动杆组件在正常和柔音模式位置之间移动处于闭合间隙的运动。
