Scale & Chord Finder
Find notes and chords in major and minor scales. See them on a keyboard and listen to each scale or chord.
Which chords belong to a selected major or minor key?
Diatonic chords use notes from the chosen scale. Select a tonic and a major, natural-minor, harmonic-minor, or melodic-minor scale to see each degree’s triad and seventh chord. Select a chord to inspect its notes or hear a local synthesizer preview.

What are the limits and details?
The melodic-minor option is the ascending form; choose natural minor for the classical descending form. Chord membership is a music-theory reference, not a rule requiring every song to stay in one key.
Limits: the listed key tonics and four seven-note scale modes. Playback uses equal temperament and a local synthesizer.
