Wagon Wheel

The definitive four-chord campfire song. Wagon Wheel loops the four most useful chords in guitar — here's the theory and why everyone can sing along.

Old Crow Medicine Show / Darius RuckerFolk & Country· Key: G major (or A with a capo)Theory analysis

🎸 Often played with a capo on fret 2 (G shapes) to reach the sung key of A.

How to find the key: It's in G major (capo 2 to sing it in A). The loop G–D–Em–C is I–V–vi–IV, all from the G family, endlessly circling home to G.

Why it works

Wagon Wheel is the I–V–vi–IV loop (G–D–Em–C) — the same four chords behind countless pop hits, here in a rolling country strum.

Because the loop never really ends (IV pulls straight back to I), it's infinitely singable — perfect for a call-and-response campfire chorus.

Master these four open chords and their switches and you can busk for hours.
