"All Blues" is a jazz composition by Miles Davis first appearing on the influential 1959 album Kind of Blue. It is a twelve-bar blues in 68; the chord sequence is that of a basic blues and made up entirely of seventh chords, with a ♭VI in the turnaround instead of just the usual V chord. In the composition's original key of G this chord is an E♭7. "All Blues" is an example of modal blues in G mixolydian. While originally an instrumental piece, lyrics were later added by Oscar Brown Jr.
