Can't Help Falling in Love
One of the most-loved wedding songs in the world — and its melody is even older than Elvis. Here's the key and the gentle descent that makes it timeless.
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 verse walks a descending line from C, harmonised C–Em–Am–F–G. Falling basslines feel graceful and resigned — exactly the mood of the lyric.
The melody actually predates Elvis: it's based on the 1784 French tune Plaisir d'amour (long in the public domain). Elvis's arrangement is what's copyrighted.
It's a beautiful first study in how bass movement, not fancy chords, can carry a song.
