Organ Grinder. A street organ played by an organ grinder is an automatic mechanical pneumatic organ designed to be mobile enough to play its music in the street.
   The two most commonly seen types are the smaller German and the larger Dutch street organ. The first descriptions of the street organ, at that time always a barrel organ owing to its use of a pinned cylinder to operate levers and play notes, can be found in literature as early as the late 18th century.
   Many were built by Italian organ builders who had settled in France and Germany, creating companies such as Frati, Gavioli, Gasparini and Fassano. These early organs had more pipes than the serinette, could play more than one tune, and were considerably larger, in sizes up to 75 cm long and 40 cm deep.
   Wooden bass pipes were placed underneath the organ and on the front were often mounted a set of pan-flutes or piccolo pipes, with decorative finishes. In many towns in Europe the barrel street organ was not just a solo performer, but used by a group of musicians as part of a story-telling street act, together with brightly coloured posters and sing-along sessions.
   In New York City, the massive influx of Italian immigrants led to a situation where, by 1880, nearly one in 20 Italian men in certain areas were organ grinders. The barrels used were heavy, held only a limited number of tunes, and could not easily be upgraded to play the latest
