A chord finder (also called a "reverse chord lookup" or "chord identifier") is a tool that tells you the name of a chord based on the notes you're playing. Instead of looking up "C Major" to see the fingering, you do the opposite—you input the fingering and get the chord name.
Traditional chord charts go from name → shape. This tool goes from shape → name.
Understanding chord names helps you communicate with other musicians and write charts.

This guitar chord identifier works by analyzing the intervals between the notes you select. Here's how to use it:
Chords are built from intervals related to a root note. Major chords use a Root, Major 3rd, and Perfect 5th. Minor chords flatten that 3rd. This tool calculates these distances automatically.
Click the fretboard above to place your fingers exactly as you would on a real guitar. Once you've selected 3 or more notes, our algorithm will instantly identify the chord name.
Our chord finder recognizes Major, Minor, 7th, Major 7, Minor 7, Sus2, Sus4, Diminished, Augmented chords, and their inversions (slash chords).
Some note combinations can be named differently depending on which note is considered the root. For example, C/E (C major with E in the bass) could also be seen as an Em voicing.
Not every combination of notes has a standard name. You might have found a 'cluster' or a partial voicing. Try adding a root note or removing color notes to simplify.
The chord theory applies universally! While this tool is optimized for guitar, the chord names are the same for piano, ukulele, or any instrument.
