This article explores young children's rhythmic, musical, aesthetic and playful creative communication in an early childhood education centre. Young children's communication is musically rhythmic and social. The data, presented as "events", formed part of an ethnographic-inspired study conducted by the researcher as a participant observer. Cultural-historical activity theory (CHAT) framed the methodology, with mediated activity as the unit of analysis. Critical and related aesthetic theory inform the data analyses, providing open ways of appreciating diversity in young children's aesthetic experience. The collaborative nature of young children's rhythmic musicality is explored and the article suggests that rhythm pervades young children's creative and communicative playfulness.
