For you theory buffs out there I thought I’d like to talk a bit about the structure of the chord progression of Autumn Leaves. The progression of the song follows a pattern of ascending 4ths. What I mean by this is that from the first chord, Am we move to D7. D is 4 steps away from A in the G major scale, the song is in the key of G major (relative minor scale – Em). From D7 we move to G, again 4 scale steps, and then from G to Cmaj7, again 4 scale steps. With a couple of exceptions this is the pattern followed right through the song. The result is that we have progression of great symmetry and balance……maybe comparable to the growth structure of those falling leaves ? Discuss
