Chichimeca is a historical term applied to different peoples of northern and central Mexico and does not designate a single cultural identity. Archive items may use it in older titles, historical descriptions, or references to specific communities such as the Chichimeca Jonaz. This category makes those materials discoverable without assuming that all share one musical tradition. For each recording, it is important to distinguish the designation used by the source, the people being described, and the repertoire’s context. Historical names should be read alongside present-day community identifications rather than treated as sufficient evidence of musical or linguistic affiliation.
