A pedal is a foot-operated mechanism found on musical instruments like pianos, organs, and harps. Pedals are used to control various functions of the instrument, such as sustaining notes, altering dynamics, or changing the sound. For example, on a piano, the sustain pedal lifts all the dampers off the strings, allowing notes to continue ringing even after the keys are released. On an organ, pedals can control different stops or effects. The use of pedals allows musicians to modify and enhance their performance with greater expression and control.
