The Music Genius Progression Lab builds chord progressions from a key, a scale, a genre and a mood. Every progression is voiced on a piano keyboard, played back in time, and comes with a plain-English explanation of why it works — the cadence, the voice-leading, and the chords doing the pulling.
Pop, lo-fi, cinematic, jazz, neo-soul and blues grammars across major, minor, dorian, mixolydian, lydian and phrygian. Free to use without an account. A free account removes the trial cap; Pro adds extended chords, smooth voice-leading, eight-bar forms, MIDI export and a saved library.
