Piano Chord Finder and Identifier
Select or enter notes to identify exact and possible piano chords.
Selected: C, E, G Bass: C
Text equivalent: Selected notes with C in the bass: C · E · G.
Exact pitch-class sets
Incomplete interpretations
Exact pitch-class sets appear first. Different roots or spellings can describe the same sounding set, so the finder reports ambiguity instead of pretending context proves one label. It never requests microphone access.
Piano Chord Finder and Identifier
Select between two and six pitch classes. Exact matches appear first; incomplete or ambiguous sets remain clearly labelled as possibilities.
Select G, B, D and F to identify G7. If B is treated as the bass, the same pitches form first inversion.
Read the result
The text answer, formula and labelled visual are equivalent views of the selected state. A set of notes can support more than one chord name, especially when tones are omitted or the harmonic root is unclear.
Connected theory
Follow the selected root or tonic into its hub, then into the relevant key, interval or inversion reference. Contextual links use the active subject rather than the same generic list on every page.
Try a controlled comparison
Change one selector at a time and describe what changed in the notes, degrees, bass or signature. Generated audio is optional and user initiated.
- Keep the root fixed and change quality.
- Keep the structure fixed and transpose.
- Compare the visible text with the keyboard.
