Zydeco is black Creole music that is native to Southwest Louisiana. It originated as a unique and distinct art form after the early 1900s.
Zydeco music is characterized by the use of an accordion as the lead instrument, and occasionally, the use of a metal washboard or “frottoir.” Over the years, zydeco has been influenced by blues and R’n’B music. It remains popular in southern Louisiana and east Texas, but people in other parts of the country, especially young people, might not even know what it is.
Early zydeco made heavy use of French lyrics, but as the use of the language has declined throughout southern Louisiana, new Zydeco music is almost exclusively in English.
Zydeco has developed its own hand-dancing form, and this is a nice video of couple strutting their stuff on the Louisiana Zydeco Live television show:
I also like this zydeco line-dance video:
The music on the above video is from top zydeco band Brian Jack & The Zydeco Gamblers.
