The origins of skiffle are obscure but are generally thought to lie in African-American musical culture in the early 20th century. Skiffle is often said to have developed from New Orleans jazz, but this claim has been disputed. Improvised jug bands playing blues and jazz were common across the American South in the early decades of the 20th century. They used instruments such as the washboard, jugs, washtub bass, cigar-box fiddle, musical saw and comb-and-paper kazoos, as well as more conventional instruments, such as acoustic guitar and banjo.
