Chord progression generator

Choose how it should feel (sad, happy, epic…) or a genre, and a key. You get a four-chord progression with its harmonic function, and it plays right away.

How it picks the chords (no AI)

Each mood and genre has a mode (major or minor), the chords it uses most and the ones it likes to start on. The generator tries every four-chord loop with that vocabulary and scores it: V wants to go home to I, a secondary dominant must reach its target, no chord repeats back to back, and rock may step down from V to IV. It shows you the best ones and never repeats the last.

What it does not do

  • It does not use AI or write the song: it suggests chords from harmony rules, and the melody and lyrics are yours.
  • It does not make audio to release: the sound is a simple guide for trying ideas.
  • It does not analyse existing songs or tell you which hit uses a progression: chords have no owner and repeat across thousands of songs.
  • It saves nothing and sends your choices to no server: everything happens in your browser.

Frequently asked questions

How do you make a chord progression?

Start on the tonic (I in major, i in minor), move through a subdominant chord (IV, ii or ♭VI) and a dominant one (V or ♭VII), and come back. With that idea of home, departure, tension and return, four chords are enough for a verse or a chorus.

What chords sound sad?

Those of a minor key: i, iv, ♭VI, ♭III and ♭VII. In A minor, Am–F–C–G or Am–Dm–Am–E. If the song is in major, start on vi or borrow the minor iv (F minor in C).

Are chord progressions copyrighted?

Generally not. A chord progression on its own has no owner: I–V–vi–IV is in thousands of songs. What is usually protected is the melody, the lyrics and the specific recording, so you can use any progression from this generator.

What do the Roman numerals mean?

They show the scale degree each chord is built on: I is the first, V the fifth. Upper case is a major chord, lower case a minor one, and ♭ means a half step lower. That way the same progression works in any key.

Can I use the progression in my song and keep it?

Yes. Copy it with its chord chart, open it in the chord progression player to change the tempo, write lyrics bar by bar and record a take, or send it to the chord sheet maker. Nothing stays saved on the website when you close the page.
