Key Features
Discover what makes Chord Progression Builder exceptional
Any Key, Any Mood, In One Prompt
Ask for "dreamy neo-soul progression in F# major, 80 BPM" or "dark minor-key cinematic progression in D minor." The Chord Progression Builder picks voicings, inversions, and rhythmic hits that match the mood — not just a list of chord symbols.
Piano, Guitar, Synth, or Full Band
Choose how the progression is voiced: solo piano for ballad writing, clean electric for indie, warm Rhodes for neo-soul, synth pads for EDM, or a full arranged band with drums + bass + chords if you want a ready-to-sing-over loop.
Classic Progressions and Unexpected Turns
Ask for a I–V–vi–IV pop loop, a ii–V–I jazz turnaround, a vi–IV–I–V sad-ballad progression, or a 12-bar blues — or describe a vibe and let the AI pick surprising but musical changes (modal interchange, secondary dominants, deceptive resolutions).
Loopable Audio You Can Write Over
Every progression is rendered as clean, loopable audio you can download and drop into a DAW, use as a writing loop, or sing melodies over. On paid plans the output is royalty-free for original songwriting and commercial release.
Frequently Asked Questions
Everything you need to know about Chord Progression Builder
A chord progression is a sequence of chords played in a repeating pattern — the harmonic backbone of a song. I–V–vi–IV (the "axis of awesome" pop progression), ii–V–I (the jazz turnaround), and 12-bar blues are three of the most-used progressions in Western popular music.
Yes. You can prompt with chord symbols ("Cmaj7 – Am7 – Dm7 – G7"), Roman numerals ("I–vi–ii–V in C"), or just describe the feel ("sad indie progression with a surprising turn"). All three approaches work.
Pop, rock, jazz, blues, R&B, neo-soul, lofi, hip-hop, EDM, house, cinematic, and more. Each genre has its own harmonic vocabulary (pop leans major, jazz uses seventh and extended chords, EDM sticks to simple minor-key loops) and the builder follows the conventions of whatever you ask for.
Yes. Chord progressions themselves aren't copyrightable (I–V–vi–IV is used in hundreds of hits), and on paid plans the rendered audio is royalty-free and cleared for use as a writing loop, a sampled element, or the harmonic bed of a commercial release.
