This article discusses the impact of arts socialization on participation in arts. Arts participation is characterized by large social inequalities. We focus on early arts socialization by parents and later socialization at school and discuss two models that explain the link between social inequalities and arts socialization: the cultural reproduction model and the cultural mobility model. The models differ in the importance they attach to early socialization by the parents and later socialization in schools. In addition, we discuss the status theory and the information theory, which explain effects of arts socialization, respectively, by social context and cognitive capacities. Finally, we review some relevant empirical studies, noting their substantive findings and/or methodological shortcomings.
