As the first collection of new work on sound and cinema in over a decade, Lowering the Boom addresses the expanding field of film sound theory and its significance in rethinking historical models of film analysis. The contributors consider the ways in which musical expression, scoring, voice-over narration, and ambient noise affect identity formation and subjectivity. Lowering the Boom also analyzes how shifting modulation of the spoken word in cinema results in variations in audience interpretation. Introducing new methods of thinking about the interaction of sound and music in films, this volume also details avant-garde film sound, which is characterized by a distinct break from the narratively based sound practices of mainstream cinema. This interdisciplinary, global approach to the theory and history of film sound opens the eyes and ears of film scholars, practitioners, and students to film's true audio-visual nature.
