First attested in the early 18th c. as a verb meaning “to press, be pressed, be wedged in”. Compare dialectal jammock (“to press, squeeze, crush into a soft mass, chew food"; also "a soft, pulpy substance”). Perhaps from Middle English chammen, champen ("to bite upon something, gnash the teeth"; whence modern champ, chomp), of uncertain origin; probably originally onomatopoeic. The "performance" sense is first attested with regards to jazz in 1929, and its origin, though uncertain, is likely metaphorical, "something sweet made by the combination of many things", with influence from jamboree.
