jam session的词源

英文词源

clambake (n.)

1835, American English, from clam (n.) + bake (n.). By 1937 in jazz slang transferred to "an enjoyable time generally," especially "jam session."

jam (n.2)

"a tight pressing between two surfaces," 1806, from jam (v.). Jazz meaning "short, free improvised passage performed by the whole band" dates from 1929, and yielded jam session (1933); but this is perhaps from jam (n.1) in sense of "something sweet, something excellent." Sense of "machine blockage" is from 1890, which probably led to the colloquial meaning "predicament, tight spot," first recorded 1914.
