Progression: Bbmaj9 — Cm9 — Dm7 — Ebmaj9
This is a sophisticated 4-bar MIDI loop designed for Acoustic Piano or Rhodes. It captures the essence of a "church-to-soul" transition, characterized by a smooth, diatonic climb in Bb Major. Unlike traditional loops that resolve downward, this progression creates a sense of "lifting" or opening up as it ascends the scale.
The sequence follows an ascending diatonic path within the key of Bb Major:
| Bar | Chord | Harmonic Function | Root Note |
|---|---|---|---|
| Bar 1 | Bbmaj9 | I (Tonic) – The Home Base | Bb |
| Bar 2 | Cm9 | ii (Supertonic) – The First Step Up | C |
| Bar 3 | Dm7 / D7 | iii (Mediant) – Increasing Tension | D |
| Bar 4 | Ebmaj9 | IV (Subdominant) – The "Lifted" Resolution | Eb |
"The secret to the Donny Hathaway sound is the 'Gospel Spread'—staggering the notes of the right-hand chord by 8–14 ticks so they roll into each other rather than hitting all at once."
