Piano

A piano was a musical instrument invented on Earth. It used metal strings that were struck by padded hammers to produce sound. The sound was controlled by a keyboard of 88 keys, typically played by a single operator using both hands. While pianos could take a number of different shapes and sizes, they were typically built inside large, very heavy wooden cabinets that functioned both as casing and sound chamber.
