Identify a chord from note names

Enter pitch names separated by spaces or commas. Common triads, suspended chords, sixths and seventh chords are matched by pitch class; enharmonic spelling and advanced jazz/altered chord naming can have multiple valid interpretations.

Chord notes

—Unique pitch classes

ReadyEnter at least two valid note names.

Browser-local music practice workflow

v10.79 connects timing, tuning, pitch reference, virtual instruments and music-theory tools without requiring an account. Existing interactive engines remain intact while the new workflow makes it easier to move from a practical task—keep time, tune, play, identify, transpose—to the next relevant tool.

Audio and theory boundaries

Microphone pitch detection depends on the device, room and signal quality. Equal-tempered frequency math does not measure a real instrument, and chord/scale naming can have multiple enharmonic or theoretical interpretations. Reference tones and noise should be used at comfortable playback levels; browser controls do not measure sound-pressure exposure.
