Concept

Loom is a text-first language for writing musical structure as readable score-like code.

Core Ideas

• Markdown-like structure: headers for tracks, frontmatter for metadata.
• Sparse piano-roll style: write only required rows.
• Elastic grid: timing is inferred by equal subdivision within bars.
• Nested cycle: [...] enables recursive subdivision.
• Stateful sustain: ties can continue across block boundaries.

Syntax Mental Model

• ^: trigger note
• .: rest
• -: sustain previous note
• |: time boundary
• [...]: nested subdivision

Whitespace is visual and non-semantic.
