Parameters: (1) surface geometry — width sufficient for a full folio (typically 40-45 cm), adjustable tilt from near-horizontal to steep; (2) support — a post (fixed, telescoping, or articulated) on a stable base; (3) page-holding mechanism — a clip, bar, or weighted edge that keeps pages from lifting under performer movement or air; (4) mounting class — floor, desk, or wall. Persistence mechanism: manufactured in bulk from wood, MDF, aluminum, or plastic, distributed through retail and music-store channels, maintained through consumer ownership cycles; the form persists as a product category via continuous production, design iteration, and replacement.
