How to identify a chord from notes
1. Select the pitch classes
Choose the distinct notes in your chord, such as C, E, and G. Octave duplicates are not needed.
2. Compare matches
The chord identifier matches your selection against common triads, suspended chords, sevenths and other formulas.
3. Find a fingering
Use our guitar, piano, and ukulele chord charts to learn how to play it.
What if multiple chords match?
The same pitch classes can have different valid names depending on root, inversion, key and harmonic context. This tool reports exact pitch-class set matches; it cannot infer the bass note or musical function from selected notes alone.
