Melody to Chord Progression Matcher

The Melody to Chord Progression Matcher finds chords for a tune you already have. Pick the key, tap the melody on the keyboard or type the note names, and the tool splits the melody into bars, scores every diatonic chord against the notes in each bar, and ranks common progressions by how well they support your melody. Play any suggestion to hear the melody over the chords.

It also shows the best three chords for each part of the melody individually, so you can mix and match if the top progression is close but not quite right.
