"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 6/4; the chord sequence is that of a basic blues and made up entirely of 7th chords, with a ♭VI in the turnaround instead of just the usual V chord. In the song's original key of G this chord is an E♭7. "All Blues" is a modal blues, meaning that the scale is a modal scale. In this case the 7th of the G major scale is flattened, so it is a mixolydian mode. A cover was made by Ron Carter on his album All Blues which came out in 1973.
