The core content of the research and analysis is about these folk communities distributing evenly over the relatively small regions, which have beliefs in common local gods and are linked with each other through consanguinity and geo-ethnic connections.Based on the strict field work and specific research of the past and present, the dissertation impersonally describes and analyses the specific cultural lives of the members in the associations, their interrelated affairs, the inheriting of musical culture, and the systems and framework of the communities. Through the objective analysis of the folk artists' apprehension of traditional culture, the reflections of the unitary regional culture inevitably suffering conflicts and impacts during the process of the urbanization of countryside, and the descriptions of various existing forms of the original folk musical associations during the process interwoven with continuity and variation, the dissertation strives to present the complete and vivid panorama of the framework and the cultural lives of folk musical associations in ordinary towns of North China, and make interpretations and draw conclusions in the perspectives of ethnomusicology, sociology, anthropology, and folklore.The dissertation is based on the structure of "summarizing-analyzing-summarizing".
