Chordophones produce sound through the vibration of stretched strings. Violins, guitars, harps, and other string instruments may be bowed, plucked, or struck, and their musical roles change across repertoires. In Mexico they appear in regional sones, popular ensembles, concert music, and experimental practices, among many other settings. This category groups recordings by the instruments’ acoustic principle and uses subcategories to distinguish construction, tuning, and playing techniques where the catalog provides that detail. A string instrument alone does not identify a tradition; the performers and context of each recording remain essential.
