Cool Barrel Organ Player!

Cool Barrel Organ Player!
The barrel organ was the traditional instrument of organ grinders.
The term hurdy gurdy is sometimes mistakenly applied to a small,
portable barrel organ that was frequently played by
organ grinders and buskers.
A barrel organ (or roller organ) is a mechanical musical
instrument consisting of bellows and one or more ranks
of pipes housed in a case, usually of wood, and often
highly decorated. The basic principle is the same as a
traditional pipe organ, but rather than being played by
an organist, the barrel organ is activated either by a person
turning a crank, or by clockwork driven by weights or springs.
The pieces of music are encoded onto wooden barrels
(or cylinders), which are analogous to the keyboard
of the traditional pipe organ.
The size of the barrel will depend on the number of notes
in the organ and the length of the tune to be played.
The more notes, the longer the barrel.
The longer the tune, the greater the diameter.
