| has gloss | eng: A barrel piano (also known as a "roller piano") is a forerunner of the modern player piano. Unlike the pneumatic player piano, the barrel piano was usually 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. |
