Blues is a genre and musical form originated by African Americans in the Deep South of the United States around the end of the 19th century. The genre developed from roots in African musical traditions, African-American work songs, spirituals, and folk music.
Blues is about tradition and personal expression. At its core, the blues has remained the same since its inception. Most blues feature simple, usually three-chord, progressions and have simple structures that are open to endless improvisations, both lyrical and musical. The blues grew out of African spirituals and worksongs.
