Free Music Tools
Three free tools for working chords out: an interactive circle of fifths, a labelled virtual piano, and a chord finder covering every chord with its notes, playback and inversions. Nothing to install, no sign-up.
Guides
Walkthroughs for each tool, and the chord theory behind them. If you would rather start from a whole progression than a single chord, the chord progression generator writes one from a description and plays it back.
