My concern here is mainly children's practice on the piano, so-called, piano culture and its parent-child relations. I would like to emphasize certain similarities of piano culture in the type of modern family. Piano culture existed from the very era when the modern family was formed, and was supported historically by the modern family both in the West and the East. Modern family has an ascetic Ethos to the education of children in the family. So, it is not unreasonable to think that piano culture is a symbol of modern family and a device to perform modern family. I attempted to adopt Kamakura city for my case study and interviewed 10 residents. It is generally considered that the socialization in modern family had a feature that the parent played a main role in socializing the child. With the advent of historical and economic developments, the parent-child relation have been diversified. The conclusion is that parents tend to desire the child-centered socialization or have the child take his or her own responsibility and control by himself or herself.
