Chord Progression Generator
Generate useful chord progressions by style, with enough harmonic guardrails to avoid random chord soup.
A concise four-bar phrase with strong functional movement and practical looping potential.
About this tool
The Chord Progression Generator creates style-aware progressions instead of pulling unrelated chords from a hat. Each result is built from curated harmonic templates, then transposed into your selected key.
Simple settings stay close to familiar diatonic movement. Colorful and adventurous settings can introduce borrowed chords, richer extensions, or secondary dominants, but the progression still keeps a clear sense of direction.
Use your ear
These are starting points for writing, practicing, and arranging. Change a chord, repeat a bar, or simplify the voicing when the song asks for it.
Why numerals help
Roman numerals show the function behind the chord names, so you can move the same idea to another key or spot why a borrowed chord works.
