This study is the first to examine the prosodic structure of everyday sung language and its relevance for language acquisition. Using extensive authentic recordings in German, Russian and French, the author demonstrates how language and music interact with each other and how singing promotes small children's acquisition of language. The book provides far-reaching insights into the interfaces of language and music, and is thus of interdisciplinary relevance. In addition, it offers entry-points into language acquisition research, speech therapy and language typology.
