Skeleton Crew — Song Skeletons, Bar by Bar
Skeleton Crew generates song skeletons: the form, the arrangement and the moments in between, laid out bar by bar as a flat graphic score. It’s a starting point for writing or producing when you know the vibe but not the shape.
Features
- Pick a style — indie rock, synth-pop, folk/Americana, neo-soul/R&B, hip-hop, cinematic/post-rock and more — and a mood, and get a full song form with sections, bar counts, tempo and an energy curve.
- Every section gets a track grid showing which instruments play, the feel (driving eighths, half-time stomp, ghost-note pocket…) and the fills and transitions that lead into the next section, placed on specific bars and beats.
- Level-bar faders shape the form, motion, texture and detail. Lock the sections you like and reroll the rest, or reroll a single section or transition.
- Rearrange the structure, then save songs to a vault in your browser.
- A single self-contained HTML page — no install, no dependencies.
Built with AI
This app was built with AI. I made it together with Claude, Anthropic’s AI assistant. I brought the songwriting and arranging knowledge — the styles, forms, feels and fills it draws from. Claude wrote the code, and I directed the design, made the product decisions and tested everything in the browser.
