"Milestones" is a
jazz composition written by
Miles Davis. It appears on the album of the same name in 1958. It has since become a
jazz standard. "Milestones" is the first example of Miles composing in a
modal style and experimentation in this piece led to the writing of "
So What" from the 1959 album
Kind of Blue. The song's modes consist of G Dorian for 16 bars, A Aeolian for another 16 bars, and then back to G Dorian for the last eight bars, then the progression repeats.
