This collection offers an in-depth study of music's narrative functions in radio drama, whether original or adapted, alongside speech and sound. It features a range of historical perspectives as well as case studies from Australia, Europe and North America, highlighting broadcasting institutions such as the BBC, RAI, ABC, WDR and SWR, from early radio to the medium's postwar golden age and contemporary productions. Not limited to classical or popular music, the chapters also pay attention to electronic varieties and musical uses of language, in addition to intermedial exchanges with other art forms such as theatre, opera and film. In doing so, the present volume sits at the crossroads of various disciplines: musicology, narratology, history, literary, media, sound and radio studies.
