pedal

A pedal is a foot-operated lever or electronic device used with musical instruments. In instruments like pianos and organs, pedals control mechanisms that alter the sound, such as lifting dampers to allow notes to sustain. For electronic instruments like electric guitars and keyboards, pedals are electronic devices that modify the instrument's signal to create various sound effects, such as distortion or reverb. The modern pedal harp uses pedals to change the pitch of strings, allowing for a wider range of notes. These devices give musicians greater control over their instrument's sound and performance capabilities.12345
