the sustain pedal is a pedal pressed with the foot that lifts all the dampers on a piano allowing every note to ring or sustain. It allows for smoother passages in musical phrases, as well as adding colour and expression into the music being played. On an acoustic piano, the susatin is the right-most pedal. On a Rhodes or Wurlitzer, it is the only pedal. Hohner Clavinets and Pianets do not have a sustain pedal.
