A piano consists of a wooden structure in which sound resonates, or is
made louder. Steel strings of different thicknesses, cut to different
lengths, are used to produce notes of higher and lower pitches. When a
player presses a key on the keyboard, a hammer inside the piano
strikes a string and then withdraws again immediately, allowing the
string to vibrate and produce sound. The sound is amplified by a
wooden soundboard, so the sound can be heard throughout an entire
concert hall.
