The piano is a complex instrument composed of many parts. The keys are the white and black keys that are pressed to create sound. The hammers are the mechanisms that strike the strings when the keys are pressed. The LEGS are the supports that hold the piano in place. The WIRES are the strings that vibrate when the hammers strike them. The dampers are the mechanisms that stop the strings from vibrating when the keys are released. The PEDALS are the foot-operated levers that control the sound of the piano.
