The story

Two chords into Kind of Blue, Bill Evans answers the bass with a five-note structure — three perfect fourths capped with a major third — and jazz piano acquires its most famous single voicing. The genius of the grip is that it's portable: plant it on the ii root and you get a luminous m11; plant it on the V root and the fourths read as a suspended dominant with a dark ♭3-as-♯9 shadow in it (the same color Herbie Hancock later floated through "Maiden Voyage"); plant it on the 3rd of the I chord and the identical shape becomes a rootless maj13. One hand position, three functions — modal harmony's whole thesis in miniature. Notice the top line: it rises a fourth, then settles down a minor third, a real melody made of nothing but the voicing itself. Let every note ring; this structure is about resonance, not punch.
