The Sir Duke chord EXPLAINED

My debut album UNDER AN EMPTY SKY is out now on VINYL, CD and DOWNLOAD: https://davidbennettpiano.bandcamp.co... Musicians have wondered for five decades how this Fm7 chord can work so well in "Sir Duke". Well today, I'm going to explain not only how Stevie Wonder makes this chord work, but also how he used it in another classic song, "Golden Lady". ii V I chord progressions explained:    • Songs that use 2 5 1 chord progressions   The on-screen piano and chords tool I used in this video is Chordwatch!
