Guitar Chord Finder — Real Fingerings & CAGED Voicings

Choose any root and any of 29 chord types — from plain major to maj9, 13ths and the Hendrix 7♯9 — and the tool shows a real fingering on the neck, the notes spelled correctly for the key, the interval recipe, and the same chord mirrored on a piano. The CAGED map shows the five shapes of the same chord up the neck, and the inversions gadget rearranges any chord with a different note in the bass, with the slash-chord name explained.

Because the chord is built live from stacked thirds, the tool can also tell you things a static chord chart cannot: whether the chord contains a tritone (the tension that makes dominant chords want to resolve), and an A/B button that plays any two chord types on the same root back to back so you can hear exactly what one added note changes. On bass it lights the chord tones for outlining basslines; on ukulele it finds genuinely strummable four-string shapes.
