This work studies the conventions of music scoring in major film genres (e.g., science fiction, hardboiled detective, horror, historical romance, western), focusing on the artistic and technical methods that modern composers employ to underscore and accompany the visual events. Each chapter begins with an analysis of the major narrative and scoring conventions of a particular genre and concludes with an in-depth analysis of two film examples from different time periods. Several photographic stills and sheet music excerpts are included throughout the work, along with a select bibliography and discography.
