Membranophones produce sound through a stretched membrane set into vibration by striking, rubbing, or other movement. Drums of different sizes, shapes, and materials appear in Mexican celebrations, dances, bands, and musical ensembles. Depending on the setting, rhythmic patterns may guide dance steps, organize accompaniment, or mark ceremonial moments. This category groups records associated with membrane instruments and distinguishes specific variants through its subcategories where the catalog permits. The acoustic classification does not mean that all drums share the same history, playing technique, or cultural function.
