How jazz pianists voice them
- 7ths everywhere: major 7 on I and IV, minor 7 on ii, iii and vi, dominant 7 on V. Triads alone sound like pop.
- Rootless voicings: the bass plays the root, so the piano plays 3–5–7–9 (for Dm9: F–A–C–E).
- Guide tones: the 3rd and 7th carry the harmony. From Dm7 to G7, the C (7th of Dm) falls a half step to B (3rd of G7). Move those voices smoothly and every progression sounds right.
- Walking bass: quarter notes, chord tones on the beat, a chromatic step into each new root.
