Zydeco is an indigenous music of Louisiana that evolved from rich and diverse cultural origins. It developed from the music of French speaking people of color in Louisiana. In the 30s and 40s, this music was very similar to Cajun music, but after WWII it began to take on different influences, including blues and rock and roll. While the fiddle is generally absent, Zydeco added the accordion, electric guitar and bass, drums, sometimes a saxophone, and it employs a distinctive corrugated metal rubboard called a frottior.
