The interior of a piano is a complex mechanism centered around the soundboard, a large wooden panel that amplifies the vibrations of the strings. Strings, varying in length and thickness to produce different pitches, are stretched across a cast iron frame, which withstands the immense tension. When a key is pressed, a hammer, part of the action mechanism, strikes the corresponding strings. Dampers, felt-covered blocks, silence the strings when the key is released. The action, a complex system of levers and pivots, translates the keystroke into the hammer's movement. All these components work in precise coordination to create the rich, resonant sound of the piano
