"Dippermouth Blues" is a song first recorded by King Oliver's Creole Jazz Band for Gennett Records in April 1923 and for Okeh Records in June of that same year. It is most often attributed to Joe "King" Oliver, though some have argued that Louis Armstrong was in fact the composer. This is partly because "Dippermouth", in the song's title, was a nickname of Armstrong's. The song is a strong example of the influence of the blues on early jazz. There is a twelve-bar blues harmonic progression, with frequent bent notes and slides into notes.
