The other day I was listening to The Mission, the NBC News theme, also written by Williams. At 2:29 into the theme, he ends a phrase with three fantastic chords. When I first heard these chords, my head split open because they are so incredibly rich. I just had to figure it out.
The theme is written in Bb. If I were writing it, I'd probably use some boring old chords to return to Bb. Perhaps simply an F7 which would work but as I said would sound pretty boring. What does Williams play?
He plays an Eb maj7 with the ninth and eleventh added, The melody is on the eleventh. This is followed by an Ab maj7 also with the ninth and eleventh added. Finally he ends on Bb.
I've used this combination of chords before to return to the root chord, but with simpler versions of the chords. In C it would be F, Bb and C. But I never thought of using it the way Williams does, with the melody sitting on the eleventh of the chord. What genius!
