In the study of folklore, the folk process is the way folk material, especially stories, music, and other art, is transformed and re-adapted in the process of its transmission from person to person and from generation to generation. The folk process defines a community—the "folk community"—in and through which folklore is transmitted. While there is a place for professional and trained performers in a folk community, it is the act of refinement and creative change by community members within the folk tradition that defines the folk process.
