Regions locate recordings within territories shaped by histories, languages, population movements, and networks of musical exchange. Administrative boundaries do not always match the areas where a son, dance, or instrumental tradition circulates. Geographic classification therefore works alongside categories for peoples, instruments, and genres. States and localities help establish provenance when the available documentation supports it, without assuming that all recordings from one territory share a repertoire. Browsing by region offers a way to compare local differences and musical connections between nearby or distant places. A geographic label identifies a cataloging relationship; the individual recording remains the source for its precise performers and circumstances.
