One who earns a living by traveling around the streets of a city with a decibelious music-making contraption called a piano-organ. Some people toss coins in his hat hoping he will play more, others hoping he will go far away. The piano-organ takes its name from the barrel organ, which it resembles. Both are mechanical contrivances actuated like oversize music boxes; i.e., they have a large revolving cylinder, or barrel, studded with metal pins that trigger the tone-generating elements. The barrel-organist (a past master of that delicately modulated instrument) is required to turn the handle that turns the barrel. See entry for "Organ boys" in Princess Ida.
