Piano Roll — Shell Voicings for ii–V–I in C (guide tones)
Dm7–G7–Cmaj7 voiced as jazz pianists' shells — root, third and seventh only — so the guide tones move by the smallest steps: the seventh of each chord (blue) falls a semitone to become the third of the next (orange) — C to B, then F to E — while the roots carry the bass.
