text: Of the three pedals found on most pianos, the damper pedal on the right lifts all the felt dampers above the strings, allowing them all to vibrate freely; the left pedal shifts the keyboard and action sideways to enable the hammer to strike only one of the two or three unison strings of each tenor and treble key (the bass notes are only single-strung); and the middle pedal (generally available on grand pianos but also found on some upright pianos) usually holds up the dampers only of those keys depressed when the pedal is depressed.
