form-analysis
Musical form and structural analysis covering binary, ternary, rondo, sonata, theme-and-variations, and popular song forms. Covers formal archetypes (AB, ABA, ABACA, sonata-allegro), 12-bar blues, arch form, minimalist process forms, strophic and through-composed designs, and formal analysis methodology for both score study and listening.

# Form Analysis Musical form is the large-scale organization of a composition — how sections relate to each other, how thematic material is presented, developed, and recapitulated, and how the listener's sense of departure and return creates narrative shape. Form analysis answers the question: "What is the structural plan of this piece?" This skill covers the standard formal archetypes of Western music, popular song forms, 20th-century innovations, and a methodology for determining form through score study and listening. **Agent affinity:** bartok (arch form, folk-derived structures, formal innovation) **Concept IDs:** song-form, musical-periods, music-history ## Part I — Fundamental Formal Units ### Motive, Phrase, Period Before analyzing large-scale form, establish the building blocks: **Motive:** The smallest recognizable musical idea — a short rhythmic and/or melodic figure. Beethoven's Fifth Symphony opens with a four-note motive (short-short-short-long) that generates the entire movement. **Phrase:** A musical sentence, typically 4 bars (but 2, 3, 5, 6, or 8 are common). A phrase has a beginning, a directed motion, and a cadential goal. The phrase is the basic unit of musical

Run `npx skills add majiayu000/claude-skill-registry --skill form-analysis --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From majiayu000/claude-skill-registry, a repository with 534 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
