Jug band

The washboard and frottoir (from Louisiana French "frotter", to rub) are used as a percussion instrument, employing the ribbed metal surface of the cleaning device as a rhythm instrument. As traditionally used in jazz, zydeco, skiffle, jug band, and old-time music, the washboard remained in its wooden frame and is played primarily by tapping, but also scraping the washboard with thimbles. Often the washboard has additional traps, such as a wood block, a cowbell, and even small cymbals.

Conversely, the frottoir (zydeco rubboard) dispenses with the frame and consists simply of the metal ribbing hung around the neck. It is played primarily with spoon handles or bottle openers in a combination of strumming, scratching, tapping and rolling.

The term American folk music encompasses numerous music genres, variously known as traditional music, traditional folk music, contemporary folk music, vernacular music, or roots music. Many traditional songs have been sung within the same family or folk group for generations, and sometimes trace back to such origins as the British Isles, Mainland Europe, or Africa. Musician Mike Seeger once famously commented that the definition of American folk music is "...all the music that fits between the cracks."

American folk music is a broad category of music including bluegrass, gospel, old time music, jug bands, Appalachian folk, blues, Cajun and Native American music. The music is considered American either because it is native to the United States or because it developed there, out of foreign origins, to such a degree that it struck musicologists as something distinctly new. It is considered "roots music" because it served as the basis of music later developed in the United States, including rock and roll, rhythm and blues, and jazz. A lot of this music was created during hardships that told the story of the history.
