“Drum language” is a collection of supernatural musical meanings generated within a spiritual ecology. Shamans weave meaning through multimodal synesthetic experiences and embodied ritual actions (performances), thereby guiding believers from the secular toward the sacred. The study of spiritual musical thought aims to provide a balanced and enduring theoretical perspective for research on belief-custom ritual music. Drawing on recent fieldwork findings-particularly those concerning subsistence ethnic groups in the southwestern high mountains and gorges, as well as discoveries of shamanic sound instruments among indigenous peoples of North Asia held in ethnographic museums abroad-this paper discusses the natural sound-instrument characteristics of drum language and the contemporary cultural heritage value of spiritual musical thought.
