A chord progression generator suggests a series of chords in a key you choose, so you can hear ideas instantly and build a verse, chorus or practice loop around them. The useful ones let you set the key, mode and length, play the result back and swap chords you don't like. Ten options follow, in no particular order.
Most songwriters have a comfort zone of four or five chords. The same shapes turn up song after song, and after a while every new idea sounds like the last one.
A generator breaks that habit by handing you combinations you wouldn't have picked. The ten tools below range from simple random rollers to full songwriting software and backing-track builders. They're listed alphabetically and in no particular order, and each description comes from the tool's own website, read this week. If you make music for your brand, my piece on music collaborations in marketing is a fun read alongside this.
Chord progression generators side by side
I checked the free plan column on each tool's own website, as of Oct 2026. Yes means the site says the tool, or a plan or version of it, is free. Trial only means a time-limited trial. Not stated means the pages I read named neither, even where there's a button inviting you to start, so check the tool's own page before you sign up.

Ten chord progression generators to try
AutoChords
Best for: Picking a feel and a key, then getting a main progression plus alternatives worked out with the circle of fifths for a chorus or bridge.
Beat Kitchen
Best for: Rolling four random chords that always stay in the key, then opening them on a harmony wheel to see how they relate.
ChordChord
Best for: Building a whole song sketch around your chords, with AI help for lyrics and drum patterns plus melody and bass editors.
Chordistry
Best for: Practising over a progression, starting from presets like the Axis or a jazz turnaround and playing it back with guitar, bass and drums.
Hookpad
Best for: Songwriters who want proven progressions to insert, colour-coded chords and an AI copilot that suggests chords and melodies to fit the project.
Jukeblocks
Best for: Choosing a key, a scale such as Dorian or Lydian and a length, then getting a random progression with Roman numerals in one click.
LANDR Composer
Best for: Producers who want chord progressions generated inside their music software, along with melodies, basslines and arpeggios to match.
Musicca
Best for: Turning chords into a backing track with piano, guitar, bass and drums, with a randomise button and separate verse, chorus and bridge sections.
Piano String Theory
Best for: Composers after unusual changes, choosing the number of measures and a chromatic or diatonic mode before the app picks the chords.
ToneGym
Best for: Hearing a progression played with smooth voice leading, next to a list of popular progressions and ear-training exercises on the same site.
Which chord tool fits how you write
- Writing a full song with theory help: Hookpad.

What the U.S. Copyright Office says about chords
The U.S. Copyright Office's Compendium, the manual its examiners follow, lists chord symbols based on standard chord progressions among material it won't register. It also says that adding chords to a melody has to be new and original authorship, not simply standard chords in common sequences such as C, F, G, C.
Want AI doing the heavy lifting in your marketing?
I build the systems that handle the boring 80 percent, so you get your week back. Done properly, with the human kept in.
That's good news for anyone using a generator. A progression on its own is a shared building block, which is why so many hit songs sit on the same few changes. What makes a song yours is the melody, the lyrics, the rhythm and the arrangement you build on top, so spend your energy there.
How to turn a generated progression into a song
- Pick the mood first: a major key for bright, a minor key for darker.
- Generate four chords and loop them until one set makes you want to hum.
- Hum or sing a melody over the loop before you change a single chord.
- Write a second progression for the chorus, often starting on a different chord.
- Record a rough voice memo so the idea survives until tomorrow.
Keys, modes and Roman numerals in plain English
Roman numerals describe each chord by its position in the key, so I, IV and V in C major are C, F and G. Learn a progression in numerals and you can move it to any key that suits your voice or your instrument.
Modes change the flavour without changing the notes much. Dorian sounds minor with a lift, Lydian sounds bright and dreamy, and Mixolydian has a bluesy, rock feel. Trying the same length of progression in a few modes is one of the quickest ways to hear something new.
Chord generator mistakes to avoid
- Changing chords too fast. Most songs hold a chord for a bar or two.
- Keeping every random result. Bin anything that doesn't move you.
- Ignoring the melody. Chords support a tune; they rarely carry a song alone.
- Writing outside your range. Transpose before you record, not after.
Signs a progression is worth keeping
- You can hum a melody over it straight away.
- It still sounds good after ten loops.
- It sits comfortably in your vocal range.
- The chorus feels different from the verse.

My plain advice on chord generators
Use a chord progression generator to get unstuck, then stop using it the moment you have a progression you like. The tool's job is the first spark; the song is still yours to write.
Keep a notebook of progressions that worked, with the key and the mood, and you'll soon need the generator less. For mixing music into videos and posts, my list of free background music for Reels helps with the next step.
