Next Chord Finder AI: What Chord Comes Next?

Build a chord progression and Next Chord Finder AI shows what songwriters most often played next, learned from over half a million songs. Tap a suggestion to hear the move, or add it and keep going.

How it works

A small neural network reads your whole progression, up to 64 chords, with its style and any section you mark, and gives the chance of every chord coming next. It hears every key the same way, so a move learned in G also counts in E♭. It runs right here in your browser: nothing you play is sent anywhere.

Reading the suggestions

Back to a chord you've used, or somewhere new. Songs go back to a chord they've just used about two times in three, so those few chords would take every top spot. The tool splits them, so you also see the likeliest moves to a chord you haven't used yet.

Bolder moves. Under the likeliest chords, a third list shows rarer moves that songwriters still made.

Style. A style nudges the suggestions rather than changing them: even jazz songs mostly use pop chords. A tag marks the moves that are at least a quarter more common in the style you picked.

Change a chord. Tap any chord in your progression to hear it. Then Change shows what could go in its place, from the chords before it, and Remove takes it out. ⇄ swaps one in, and Undo steps back through every change.

Sections. Mark where a verse, chorus or bridge begins, and the suggestions change to how that part usually opens.

The reason under each chord. The key is a guess from your chords; pick it yourself in Settings if the guess is wrong. The short reasons come from music theory rules, not from the network.

How good it is

Tested on nearly 20,000 songs by artists it never saw, the chord the songwriter really played next was its first pick 74% of the time and in its top three 91% of the time.

Take it to your DAW

Settings has the tempo and how long each chord lasts, and Download as MIDI saves your progression as a .mid file with the chords and a bass line on separate tracks.
