Random Chord Generator — Four Chords, Play Them, Study the Progression

Four chords. Hit the dice, click any chord to hear it. If something grabs you, open it in the Harmony Wheel to see how the chords relate.

How it works

The tool picks four chords from a musical key and lays them out in order. Every chord you hear is diatonic — meaning it belongs to that key — so the progression will always sound musical. Click any chord to hear it on its own. Click the dice to roll a new set.

If a progression grabs you, hit Explore on the Wheel to open it on the Harmony Wheel, where you can see how the chords relate to each other, swap them for relatives, and try extensions.

Why random chord progressions are useful

Generating random chords is one of the fastest ways to break out of writing the same three songs. Most songwriters fall into chord habits — I-V-vi-IV forever. A random progression forces you to hear combinations you wouldn’t normally pick and decide whether they work.

It’s also a useful ear-training tool. Roll a progression, hum a melody over it, then look at the chord names and see if you can guess the key before checking.

What to do with the chords

• Practice: pick a random progression, loop it in your DAW, and improvise over it for five minutes
• Songwriting: use a roll as the starting point for a verse or chorus — don’t edit it until you’ve written a melody
• Ear training: try to name each chord by ear before looking at the label
• Theory study: open the progression on the Harmony Wheel and see which chords are related, which ones borrow from other keys, and why the order sounds the way it does

Learn the theory behind these chords

This tool is fun on its own, but if you want to understand why certain chord progressions work — and be able to write your own without the dice — the Musician Basics guide covers chord construction, cadences, borrowed chords, and modulation across 13 free chapters.

And if you want to work on this with instructors in a live class, Musician Basics & Ear Training runs as a live cohort on Discord. Details and enrollment.
