Chopsticks (originally named as "The Celebrated Chop Waltz") is a simple, widely known waltz for the piano. It was written in 1877 by the British composer Euphemia Allen under the pseudonym Arthur de Lulli. Allen, whose brother was a music publisher, was supposedly only sixteen when she composed the piece, with arrangements for solo and duet. The title Chop Waltz comes from Allen's specification that the melody be played in two-part harmony with both hands held in a vertical orientation, little fingers down and palms facing each other, striking the keys with a chopping motion. It was first used in the Barney & Friends episode Classical Cleanup.
