Examines children's musical practices on Corn Island, some 52 miles off the Caribbean coast of Nicaragua, which has long been a site of cross-cultural interaction and exchange. In 1987, as part of the postwar peace agreements, two autonomous regions—north and south—were established on the Caribbean coast of Nicaragua. The cultural and education aspects of autonomy came to be envisioned largely through concepts of interculturalidad, or interculturalism. Children's musical practices enter into discourses of interculturalism in several ways. They are often important symbols of the future; informal genres of vernacular expression (such as singing games) are a key resource for curricular reform that aims to bring regional folklore into the classroom; and they are central to processes of cultural interaction, exchange, and transformation. This is because children's activities are often oriented toward playful improvisation and because children are key actors in processes of socialization and adaptation to changing circumstances. Expressive practices such as music are dialogic tools through which differences are enacted, through which boundaries are constructed within and between social groups. This understanding of interculturalism as an everyday practice helps us see how culture emerges from interaction and play and how communication is accomplished using a diverse pool of resources. This essay focuses on the children of Miskitu migrants on Corn Island, particularly on singing game performance.
