How this works
Most chord tools assume you already know harmony. This one doesn't. Pick a mood and we choose a key for you, then show only the chords that belong in that key — so you literally cannot pick a chord that clashes. For each slot we rank the most likely good next chord, the same moves that power thousands of songs, and label each chord by what it does: Home (rest), Lift (movement), Tension (wants to resolve), Emotional (colour). Press play and it loops as block chords, built live in your browser with the Web Audio API — no samples, no plugins.
What's a good chord progression?
The famous one is I–V–vi–IV — bright, hopeful, and everywhere in pop. Flip the order to vi–IV–I–V for something more wistful, or drop into a minor key with i–VI–III–VII for a sad or cinematic feel. Hit Surprise me to drop a complete, known-good progression into all four slots at once — the fastest way to go from blank page to "I made something." When you've got a loop you like, jam against the metronome at the same tempo, name the exact notes with the Note & Frequency Calculator, or dig into every scale and mode in the Chord & Scale Explorer.
