The damper-pedal is an integral part of a piano that is often referred to as the sustain pedal. Its function is to sustain the notes played on the keyboard by lifting the dampers on the strings. The term damper-pedal, however, may not be commonly recognized by everyone. In such cases, it can be referred to as the sustain pedal, the loud pedal, or simply the pedal. Some musicians may also use the terms resonance pedal or una corda pedal, depending on the type of piano being played. Despite the different names, the purpose of the pedal remains the same: to create beautiful and sustained sound on the piano.
