Zydeco: Usually fast tempo and dominated by the button or piano accordion and a form of a washboard known as a "rub-board/scrub-board/wash-board," or frottoir, zydeco music was originally created at house dances, where families and friends gathered for socializing.
As a result, the music integrated waltz, shuffles, two-steps, blues, rock and roll, and other dance music forms of the era. (Wikipedia)
