Chord Progression Generator
Build a song-ready chord progression in seconds. Choose a key, mode, style, length and complexity, then get the chord names, roman numerals, diatonic chord table and alternate verse, chorus, bridge or cadence ideas you can copy into a lead sheet, DAW session or practice notebook.
How to use the chord progression generator
-
1
Choose a key and mode
Pick the tonal center and whether the progression should feel major, natural minor or harmonic minor.
-
2
Shape the song section
Select a style, chord count and complexity level so the pattern leans pop, rock, jazz, cinematic, R&B or folk.
-
3
Copy the harmony
Use the chord row, roman numerals, scale notes and alternates as a starting point for writing, transposing or practicing.
Roman numerals describe chord function relative to the key. In C major, I - V - vi - IV becomes C - G - Am - F. Move the same roman numerals to B-flat major and the idea becomes Bb - F - Gm - Eb. That is why writers, teachers and session players often talk about progressions by function first and chord names second.
The generator starts with the selected scale, stacks triads on each scale degree, then maps a style pattern onto those diatonic chords. Natural minor keeps the flat seventh common in many pop and folk loops, while harmonic minor raises the seventh scale degree so the V chord resolves more strongly back to i.
| Setting | What it changes | Example effect |
|---|---|---|
| Key | The pitch center and chord names | C major uses C, G, Am, F |
| Mode | The scale and chord qualities | A harmonic minor uses E major as V |
| Style | The order of functions | Jazz favors ii - V - I movement |
| Length | Number of chords in the loop | 4 chords for a hook, 8 for a longer phrase |
| Complexity | Chord color | Colorful mode adds tasteful extensions |
Use the first result as the main loop, then try alternates for a bridge or chorus contrast. If a progression sounds close but not quite right, keep the roman numerals and change the key, or switch between natural and harmonic minor to change how strongly the cadence pulls home.
Frequently Asked Questions
A chord progression is an ordered sequence of chords. It gives a song section its harmonic motion, such as moving from I to V to vi to IV in a major key.
Roman numerals show how each chord functions inside the key. They make it easy to transpose the same idea from C major to Bb major, A minor or any other key.
Natural minor uses the unraised seventh scale degree. Harmonic minor raises that seventh degree, which often turns the V chord into a stronger major or dominant chord before resolving to i.
No. The progressions are generated locally from music-theory patterns in the component. No audio, files or recordings are uploaded.
