A harp is a stringed instrument which has its strings anchored in the soundboard. Each string is tuned to a different note of the scale, somewhat like a piano. The strings are plucked, using the thumb and fingers of both hands.

Unlike the piano, however, most harps have only seven strings in each octave. That would limit the harp to only one key (without retuning), if it did not have a mechanism to independently change the length of the strings.

Pedal harps have metal pins mounted on rotating disks, which grab the string at the right points to shorten the vibrating length of each string, raising the pitch by one or two semitones. The disks are rotated by a system of rods connected to pedals in the base of the harp, so that the player can change key or play accidentals on the fly.

Lever harps have a cam, operated by a lever, on each string. The cam presses the string against a metal pin at the right point to shorten the vibrating length and raise the pitch by one semitone. The levers are operated by the player's left hand.
