chordgen

Chordgen is a free chord progression generator built for songwriters, producers, and beginners who want to start from a working set of chords instead of a blank page. Pick a key, mode (major or minor), style, and tempo, and it generates a progression — displayed with Roman numeral analysis, the notes in each chord, and instant audio playback — with no sign-up required and every sound kept on-device.

Beyond the fast manual generator, Chordgen includes an optional AI Composer for describing a musical idea in plain language rather than picking parameters manually, and automatically surfaces three Alternative Progressions in the same key so you can compare nearby paths (like vi-IV-I-V or I-vi-IV-V) before committing. A full chord reference for the selected key is shown alongside the generator, and finished progressions can be copied as chord names or exported directly as an editable MIDI file for use in other music software.

The tool is explicitly framed as a starting point rather than a rule — its own “Make it Yours” guidance encourages swapping chords, reordering sequences, or borrowing from an alternative progression, positioning Chordgen as a songwriting aid rather than a fully automated composition tool.

Pros and Cons

Pros

• Genuinely free with no sign-up wall — a real, complete tool rather than a locked demo
• Roman numeral analysis plus note-level chord voicings makes it useful for both music-theory learners and working musicians
• Alternative Progressions feature gives real comparative options in one click, not just a single generated result
• MIDI export means output is immediately usable in a DAW rather than requiring manual re-entry
• On-device processing for manual generation and playback is a genuine privacy plus over cloud-only tools

Cons

• Chord progression generation alone doesn’t produce a finished track — pairing with a full music generator (like Mubert) is needed for actual produced audio
• AI Composer mode’s exact underlying model/capabilities aren’t detailed on the page — treat it as a convenience input method rather than assuming deep compositional intelligence
• Best suited to common practice pop/rock/jazz harmony; unclear how well it handles more experimental or non-diatonic progressions
• No mobile app — browser-only, which is fine for desktop songwriting sessions but less convenient away from a computer

Chordgen Alternatives

• Mubert — for generating full produced tracks rather than chord progressions specifically; genuinely complementary rather than competing, since you could sketch a progression in Chordgen then produce it in Mubert

FAQ

What is a chord progression generator?

A chord progression generator creates a sequence of chords from a selected key, mode, and musical feel, helping songwriters, producers, and beginners try combinations that work together without starting from a blank page.

How do I use a chord progression maker?

Choose a key and mode, select a style, set the tempo, and generate a progression. You can preview one chord or play the full sequence, then copy the chord names or export a MIDI file for your music software.

What are the most common chord progressions?

Common progressions include I-V-vi-IV in pop, ii-V-I in jazz, and I-IV-V in blues and rock. The Roman numerals describe each chord’s position in the key, so the same pattern can be moved to any key.

Is Chordgen free?

Yes. Chordgen is free with no sign-up required — manual generation, audio playback, and MIDI export all stay on your device.

Do I need music theory knowledge to use Chordgen?

No. The tool explains Roman numerals directly on the page (uppercase = major, lowercase = minor, ° = diminished), so beginners can follow along while learning.

Can I export what I make in Chordgen?

Yes. Progressions can be copied as chord names or exported as an editable MIDI file for use in other music software.
