I–iii–vi–II7: Soulful Chain
Amaj7–C#m7–F#m7–B7 feels like a smooth conveyor belt because the roots move through closely related chords while the 7ths provide constant color. The iii chord (C#m7) keeps two notes in common with Amaj7, so the shift is silky rather than dramatic, and vi (F#m7) deepens the mood without leaving the key. Ending on B7 adds a bright dominant push that begs to return to A, which is perfect for R&B turnarounds and neo-soul loop writing. On keys, use tight left-hand roots with right-hand guide tones and a 9th; it will sound modern immediately even without extensions written. For bass, outline the roots but connect them with stepwise passing notes to glue the groove together. For melodies, lean on C# and E over the first three chords, then highlight D# over B7 to set up a satisfying resolution back to Amaj7.

Play it on guitar
Start slow, keep your right hand steady, and aim for clean changes on the downbeats. Once it’s comfortable, add a groove and increase tempo.
Capo suggestion: try capo 0 and play in A shapes for open chords.

Roman numerals & theory
Roman numerals describe the chord’s function relative to the key. This helps you transpose the “shape” to any key without memorizing new chord names.
In A major: Imaj7–IIImaj7–VImaj7–II7
Variations (keep the progression, change the feel)
- • Add 7ths for color (try maj7 on I, m7 on vi, and V7 before resolving).
- • Use a sus4 resolve on the V chord (e.g. Gsus4 → G) to create tension and release.
- • Change the rhythm instead of the chords: try anticipations (hit the next chord on the “and” of 4).
- • Arpeggiate the top notes to create a hook while the harmony stays the same.
- • Borrow a darker chord for contrast (in a major key, try iv for one bar before returning).
