Joseph Nathan "King" Oliver was an American jazz cornet player and bandleader. He was particularly recognized for his playing style and his pioneering use of mutes in jazz. Also a notable composer, he wrote many tunes still played today, including "Dippermouth Blues", "Sweet Like This", "Canal Street Blues", and "Doctor Jazz". He was the mentor and teacher of Louis Armstrong. His influence was such that Armstrong claimed, "if it had not been for Joe Oliver, Jazz would not be what it is today."

Jazz is a music genre that originated in the African-American communities of New Orleans, Louisiana, in the late 19th and early 20th centuries, with its roots in blues and ragtime. Since the 1920s Jazz Age, it has been recognized as a major form of musical expression in traditional and popular music. Jazz is characterized by swing and blue notes, complex chords, call and response vocals, polyrhythms and improvisation. Jazz has roots in European harmony and African rhythmic rituals.
