What is Chord Finder?

The Chord Finder shows guitar, piano, and ukulele chord diagrams for any root note and chord type. Free and private — pick a chord and see the fingering instantly, or click piano keys to identify a chord you already have.

Pick from the 12 chromatic roots and 18 chord qualities — major, minor, 7, maj7, min7, sus2, sus4, dim, aug, 6, m6, add9, 9, maj9, m9, 11, 13, and 6/9. The guitar view shows a fretboard diagram with finger positions, the piano view highlights the keys you press, and the ukulele view draws the GCEA tuning. Hit Play and a built-in oscillator sounds the chord so you can hear it before reaching for the instrument. Switch to Identify mode to click piano keys and read back the chord name that fits those notes.

How to use

1. Select a root note
2. Choose a chord type like major, minor, 7th, or diminished
3. Switch between guitar, piano, and ukulele views to see the fingering

When to use

• Learning a song where the chord chart only names the chord but doesn't show the shape.
• Comparing a guitar voicing against the piano voicing of the same chord while arranging.
• Settling whether Csus4 has an F or a G — without flipping through a music theory book.

Result

Look up C major: see the guitar fingering diagram and piano keys highlighted for C, E, and G.

FAQ

How do I see other voicings of a chord on guitar?

By default the guitar view opens on the most common shape that beginners and intermediates use, since that's what most chord charts assume. When a chord has other usable positions further up the neck, prev and next arrows appear under the diagram so you can step through them and pick the one that fits your hand or the song.

Are the chord notes spelled with sharps or flats?

Either way you like. There's a Sharps/Flats toggle next to the root selector. It starts on sharps (C#, D#, F#, G#, A#), and flipping it to flats re-labels the root buttons, the chord notes, and the piano keys as Db, Eb, Gb, Ab, Bb. The two spellings name the very same pitches, so the keys you press and the guitar shapes you finger stay identical.

Why doesn't the play button work on my phone?

Mobile browsers block audio until you tap somewhere on the page. Tap any control once and then hit Play — the Web Audio context will unlock and the chord will sound.

What's the difference between sus2 and sus4?

Sus2 replaces the third with the second above the root, sus4 replaces it with the fourth. Both leave the chord open and unresolved, which is why you hear them as intro chords or hold tones before a major or minor resolves.

Can I use the diagrams for a left-handed guitar?

The fretboard is drawn for a standard right-handed guitar with low E at the top. Tap the Left-handed button above the diagram and the whole fretboard mirrors for you — fret numbers stay the same, the strings just flip. It works the same way in the ukulele view.
