You may be looking for the utensil, chopstick.

"Chopsticks" was a simplistic 19th century piano waltz composed on Earth.

After hearing Seven of Nine play an intricate song on the piano for the first time, after discovering that she had just learned to play, a hologram of Chakotay responded to her performance by stating "Approve? I'm amazed. I was expecting "Chopsticks". I had no idea you were so good." (VOY: "Human Error")

This composition was credited to composer Arthur de Lulli. (Star Trek Encyclopedia (4th ed., vol. 1, p. 140))
