Free AI music prompt tool
AI Song Structure Generator
Map song sections for AI music: intro, verse, pre-chorus, chorus, drop, bridge, breakdown, outro, loopable endings, and creator background beds.
Why structure matters
AI music becomes more usable when the prompt clearly maps section purpose, energy changes, vocal placement, instrumental drops, and endings.

Structure Notes
Structure rules: - Define the job of each section. - Do not overfill lyrics. - Put the emotional peak where the listener expects payoff. - Use a clean ending unless you need a loop. - If the model wanders, shorten the structure and strengthen avoid rules.
