Chord & Scale Explorer — Real Music Theory, Not AI Guesses

Pick a root note and a scale or mode to see its notes laid out on a highlighted piano keyboard, along with the diatonic chords that scale actually produces — all computed from real music theory rules, not an AI guess at what sounds plausible. An AI pass then suggests chord progressions built from those computed chords.

How to use AI Chord & Scale Explorer

  1. Pick a root note and a scale or mode.
  2. See the notes highlighted on the piano keyboard.
  3. Review the diatonic chords the scale produces.
  4. Get AI-suggested progressions built from those chords.

Frequently asked questions

Are the chords AI-generated?
No — the notes, keyboard highlighting and diatonic chords are computed directly from music theory rules, so they are always correct for the scale you picked. AI is used only for suggesting progressions from that verified chord set.
What is a diatonic chord?
A chord built entirely from notes within the chosen scale — the natural chord set that scale produces, which is why a C major scale's diatonic chords are different from A minor's despite sharing the same notes.
Does it cover modes, not just major/minor?
Yes — modes like Dorian, Mixolydian and others are included alongside standard major and minor scales.
