Voice and singing encompass musical practices in which the human body produces sound through words, syllables, vocalizations, or nonverbal techniques. In Mexico they appear in solo songs, choirs, sung prayers, street calls, musical storytelling, and experimental work. Vocal production, language, exchanges among singers, and performance setting are important to understanding each record. This section groups materials related to vocal expression and supports comparison with the archive’s instruments and genres. Not every use of the voice is singing, and vocal practices do not all serve the same purpose.
