Chord Variations

Chord Variations is a small browser based tool that uses AI to suggest alternative versions of a chord progression. You build a progression by choosing a root note from C through B and a chord quality, then press Generate to receive variations on what you entered. It is meant as a quick source of harmonic ideas for songwriters, guitarists, pianists and producers who have a progression they like but want fresh substitutions or richer voicings. The quality list is broad. It covers major, minor, diminished and augmented triads, the common seventh chords including dominant, major, minor, minor major, half diminished and diminished sevenths, extended chords up to ninths, elevenths and thirteenths, and add9 chords. A progression can hold up to five chords at a time, and you can remove any chord with the red button. The page includes a guided tour for first time visitors and a Stop button to cancel a run in progress. Generation is not instant. The interface warns that it might take a minute to complete, and it displays an error message if a progression could not be generated, so some patience and retries may be needed. The tool runs as a simple hosted web page with no account screen visible. The vendor does not publish pricing, and no plans or paywall appear on the site, so cost is not stated.
