Barrel piano

A barrel piano (also known as a "roller piano") is a forerunner of the modern player piano. Unlike the pneumatic player piano, a barrel piano is usually powered by turning a hand crank, though coin operated models powered by clockwork were used to provide music in establishments such as pubs and cafés. Barrel pianos were popular with street musicians, who sought novel instruments that were also highly portable. They are frequently confused with barrel organs, but are quite different instruments.
