Popoluca is a designation applied to several peoples and languages in southern Veracruz and should not be understood as naming one community. In musical records, the term may appear without specifying whether the performers come from the Sierra, Oluta, or another locality. Celebrations, songs, and instrumental ensembles require their own context in each case. This category keeps recordings indexed under the historical designation discoverable while encouraging closer attention to provenance. Language, municipality, and community self-identification are essential details for avoiding mistaken cultural attributions. Similar catalogue names do not establish that the documented repertoires share a single origin.
