Piano Chord Finder: Notes, Inversions & Keyboard

Build piano chords from a root and type or reverse-identify chord names from notes, including likely inversions and interval evidence.

Notes to identify

Enharmonic spelling

Use the tool above, then review this deeper calculation.

Inversion & voicing explorer

Rotate the current chord tones above to hear how bass position changes the voicing while the pitch-class identity stays the same.

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.

Practical guide and verification

Chord identity and voicing are related but different

C–E–G, E–G–C, and G–C–E contain the same pitch classes but place different chord tones in the bass. Use the inversion explorer to hear how bass position changes the voicing without changing the basic triad identity.

Use the lowest sounding note to name an inversion

Root position places the root in the bass; first inversion places the third in the bass; second inversion places the fifth in the bass. Seventh chords add another possible inversion based on the seventh.

Enharmonic spelling depends on musical context

A black key can be named C-sharp or D-flat, and the theoretically correct spelling depends on key and chord function. The keyboard reference is a pitch-class aid, not a complete notation engine for every harmonic context.

Compare voicings at a comfortable level

Web Audio playback is a practice reference. Device volume, speakers, headphones, and browser gain affect perceived loudness, so keep playback comfortable and do not treat the generated tone as a calibrated acoustic measurement.

Use reverse identification when the notes come first

If you know the notes you are playing but not the chord name, the reverse-identification workflow is more appropriate than guessing a root and type. Bass note and key context can still make multiple names musically plausible.
