About ChordWiki
Every chord in every key, for guitar, piano and ukulele. See it. Hear it. Play it.
Why ChordWiki exists
ChordWiki started with a frustration every musician knows: stopping in the middle of playing to look up a chord shape — again. I’m a musician who did that more times than I can count, usually on a site buried in ads that showed a diagram but never let me hear how the chord should sound.
I wanted something simple: look up any chord, see exactly where your fingers go, hear how it should sound, and practice it until you don’t need to look it up anymore. So I built it.

How the chord shapes are chosen
Every chord is built from music theory — its notes, correctly spelled for its key — and the guitar and ukulele shapes are worked out from those notes: which strings and frets play them, which fingers fit, and which shapes are practical to play. Shapes are ranked so the standard, most playable version comes first, with alternatives after it. The most common chords also have hand-written notes and tips.
Guitar shapes use standard tuning (E A D G B E) and ukulele shapes use standard G C E A tuning. Left-handed? Every guitar and ukulele diagram can be flipped with the Left-handed switch.

Found a mistake? Have an idea?
If a chord shape looks wrong, something doesn’t work, or you have an idea for the site, I’d love to hear from you: hello@chordwiki.com. When reporting a chord, include the chord and instrument (for example “F♯m7 on ukulele”).
