Based on the field ethnographic investigation of Dongba rituals and Dongba funeral rituals, the author finds that in the narrative of Dongba rituals, Dongba dance, music, and painting techniques accompanied by oral chanting texts are also highly stylized. These different narrative units are constrained by the ritual theme, scene and type, and together constitute the ritual program, promote the logical development of ritual narrative behavior, and form a multimodal ritual narrative text that constructs and integrates with each other. The function of ritual program in ritual narrative is like the "big word" used by oral singers in oral performance, providing a sufficient "arsenal" for the ceremonial officiant to achieve the ritual narrative.(AI翻译)
