I–V6–vi–IV: Voice-Leading Loop
C–G/B–Am–F is a voice-leading trick that makes a simple progression sound arranged. Putting G over B turns the bass into a stepwise line (C–B–A), so the harmony feels like it is flowing rather than jumping. Functionally, you still have tonic stability, dominant energy, a relative-minor color, and the warm openness of IV, which is why it works for singer-songwriter verses, worship progressions, and fingerpicking guitar patterns. The smoothness also helps melodies: you can hold E across C and Am, or hold C across G/B and Am, and the chord change still feels active because the bass is moving. For piano, play light right-hand triads and let the left hand carry the bass steps. For writing, try delaying the F chord by half a bar; that tiny rhythmic surprise often turns into the hook of the section.

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.

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: I–V–vi–IV
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).
