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.
A style of music that evolved from southern African-American secular songs and is usually distinguished by a strong 4/4 rhythm, flatted thirds and sevenths, a 12-bar structure, and lyrics in a three-line stanza in which the second line repeats the first: The blues is an expression of anger against shame and humiliation (B.B. King).
