Sweet Home Alabama
Three chords, endless loop, unmistakable swagger. Sweet Home Alabama is a perfect lesson in the rock ‘flat-7’ sound. Here's the theory.
The chords & what each one does
Chords labelled with their Roman numeral(the chord's role in the key) and its job. Numbers, not letters — so you can move the whole thing to any key.
Why it works
The I–♭VII–IV loop (D–C–G) is the sound of Mixolydian rock — a major key with a lowered 7th. That ♭VII (C) refuses to be a polite 'leading tone', which is why it swaggers instead of resolving.
It never really lands or builds tension — it just rolls, which is exactly what a good driving-around anthem wants.
Learn this loop and you've got the DNA of a thousand rock and country-rock tunes.
