An arrangement is organized into named sections, each carrying a density/energy target and a structural function

A live-coded arrangement is organized into named sections identified by a section intent field (intro, build, drop, main, breakdown, fill, transition, outro). The teachable claim is that each section is defined by two things: a density/energy target (how sparse or full, how low or high the intensity) and a structural function (what job it does for the piece — establish, raise tension, pay off, sustain, reset, signal, morph, resolve). Naming the current material’s section is what lets both the performer and any coupled visuals key off a shared arrangement role. Section length is a genre variable: hypnotic genres (techno, dub-techno, ambient) use long gradual sections, while song-form genres delineate shorter, sharper ones.

Examples

intro: sparse, low→rising, establishes tempo/key breakdown: sparse dip mid-track — resets the ear, builds suspense main: dense, high steady — the sustained core groove

Assessment

State the two properties that define an arrangement section, and contrast the section-length convention of techno with that of vocal house.
