Chord Finder

Pick a chord to see its fingering — or tap the diagram to name what you play. Guitar, ukulele, and piano.

About Chord Finder

This tool works in both directions: forward lookup (select root + quality → fingering appears on the diagram) and reverse naming (tap the frets or piano keys → the tool resolves the pitch set to a chord name live). Note names (C D E) are universal, so language switching only affects labels — not the diagram itself.

Reading a chord diagram: ○ means open string (play open), ✕ means muted (don't play), numbers (1–4) inside dots indicate finger positions. The notation "x-3-2-0-3-0" lists fret positions for strings 6 through 1, the most common shorthand for guitarists. When no common open voicing exists, the tool generates a movable barre shape and shows a dashed outline to indicate "this shape slides up and down the neck."

Supported instruments: guitar (standard EADGBE), ukulele (standard GCEA), and piano. Supported chord qualities: major, minor, 7, maj7, m7, m7b5, add9, sus2, sus4, dim, aug. Use the ♯/♭ button (top-right) to switch note spelling between sharps and flats (a display switch only — it doesn't change the fingering). If a tapped pitch set doesn't match any supported quality, the tool shows "unknown shape" rather than guessing a wrong name.

How to use

Run a clean first pass

  1. Choose an instrument (guitar / ukulele / piano), pick a root note and chord quality — the diagram shows the fingering instantly
  2. Or go the other way: tap frets or piano keys directly, and the ribbon below names the chord and lists its notes
  3. Every tap plays the note; use the mute button in the top-right to silence audio without changing anything visual

FAQ

What people usually want to know

Which instruments and tunings are supported?

Guitar (standard EADGBE), ukulele (standard GCEA), and piano. Note names use the international standard (C D E), so switching language only changes UI labels.

Can I tap the fretboard to name a chord?

Yes. Tap any frets on the diagram and the chord ribbon resolves the pitch set to a name in real time (e.g. C E G D → Cadd9). Unrecognised sets show 'unknown shape' rather than a wrong name.

Why does the tool show a 'movable' shape for some chords?

When no common open-position voicing exists for a chord, the tool generates a movable barre shape and labels it 'movable'. A dashed outline on the diagram shows that the same shape can slide up and down the neck.

Does this require an internet connection or account?

No. All chord lookups and naming happen locally in your browser — no backend, no account, nothing uploaded.
