vi–ii–V–I: Jazz Turnaround Loop

vi–ii–V–I feels like a musical conveyor belt because each chord sets up the next with clear function. In C, Am7 has a relaxed tonic-family sound, Dm7 adds predominant motion, G7 creates dominant tension, and Cmaj7 resolves with a bright, stable color. The reason it composes itself is voice leading: keep the 3rd and 7th of each chord close and you can move between shapes by a half-step or whole step. That is why swing comping and jazz piano practice often start here. Try shell voicings first, then add a fifth or a top-note melody for color. For improvisation, outline the guide tones (C and G for Am7, F and C for Dm7, B and F for G7) and your lines will sound connected even when they are simple.

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 C shapes for open chords.

Chords: Am7 – Dm7 – G7 – Cmaj7

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 C major: VImaj7–IImaj7–V7–Imaj7

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).
