Look up a chord or identify one you're playing
The Chord Finder works both ways. If you know the name, search it to see the exact notes and how to play it. If you found a shape you like, pick its notes and the tool names it, so you can learn it, write it down and reuse it.
Guitar shapes that are checked, not guessed
Common chords show the standard shapes guitarists learn first, such as x32010 for C and 133211 for F. Every other chord gets shapes worked out for it note by note, so there's always a playable diagram, from Cadd9 to Db13.
Frequently Asked Questions
How do I identify a chord from its notes?
Open Identify from notes and pick the notes you're playing, lowest first. The tool names the chord and lists other names the same notes can have: A C E G is Am7 or C6/A, for example. Fifths and some extensions can be left out, as they often are in real voicings.
Why does it spell chords with flats sometimes and sharps other times?
Each note is spelled from the chord's root by interval, the way chord charts and sheet music write them. Eb major seventh is Eb G Bb D, and F# major is F# A# C#, so every chord tone keeps its own letter.
Does it work for both guitar and piano?
Yes. Every chord shows its exact keys on a piano and up to three guitar shapes with finger numbers, open and muted strings and barres. Each shape is checked so every string you play sounds a chord tone and the lowest one is the bass note.
Which chord types can it find?
36 types: major, minor, diminished and augmented triads; sixths and added ninths; seventh chords including major seventh, minor seventh, diminished seventh, half-diminished and augmented sevenths; ninths, elevenths (including sharp-eleven chords like 7#11 and maj7#11) and thirteenths; altered dominants like 7b9 and 7#9; suspended chords; and power chords. Slash chords such as C/E or G7/B work too.
What are the related chords and keys?
Related chords are the chords this one most often moves to or from, such as its relative and parallel minor, its dominant, or the chord a dominant seventh resolves to. The keys list shows every major and natural minor key that contains the chord, with its Roman numeral in each.
Is the chord finder free?
Yes, it is completely free with no signup and no limits.
