Progression Builder: Section-based songwriting utility

Build a verse, chorus, and bridge that belong together - and make sense on bass.

Choose a key, mode, style, and complexity, then generate a related verse, chorus, and bridge. Each section includes chord movement, numerals, bass roots, passing-note ideas, 9th / 11th color suggestions, and a neck view for one practical fingering path.

Build song sections

This tool creates section-based harmonic movement instead of a single loop. Verse stays more grounded, chorus opens up, and bridge creates contrast.
