This wide-ranging book shows how, since the first centuries of the Christian era, gentiles have associated Jews with noise. The study focuses on a “musical libel" - a variation on the Passion story that recurs in various forms and cultures in which an innocent Christian boy is killed by a Jew in order to silence his “harmonious musicality.” In paying close attention to how and where this libel surfaces, Ruth HaCohen covers a wide swath of Western cultural history. The author combines in her analysis the perspectives of musicology, literary criticism, philosophy, psychology, and anthropology, tracing the tensions between Jewish “noise" and idealized Christian “harmony” and their artistic manifestations from the high Middle Ages through Shakespeare, Bach, Wagner, George Eliot, Kafka, Schoenberg and others. She explores testimonies by outsider visitors of synagogues, operas, caricatures, and Nazi movies. Her analysis shows how entrenched aesthetic-theological assumptions have persistently defined European culture and its internal moral and political orientations. Following the publication of the book, the author received two prestigious awards: the Polonsky Award for Creativity and Originality in the Humanities, and the Kinkelday Award from the American Musicological Society for the best book in musicology published in 2011 .

The Western musical tradition has produced not only music, but also countless writings about music that remain in continuous—and enormously influential—dialogue with their subject. With sweeping scope and philosophical depth, A Language of Its Own traces the past millennium of this ongoing exchange. Ruth Katz argues that the indispensable relationship between intellectual production and musical creation gave rise to the Western conception of music. This evolving and sometimes conflicted process, in turn, shaped the art form itself. As ideas entered music from the contexts in which it existed, its internal language developed in tandem with shifts in intellectual and social history. Katz explores how this infrastructure allowed music to explain itself from within, creating a self-referential and rational foundation that has begun to erode in recent years. A magisterial exploration of a frequently overlooked intersection of Western art and philosophy, A Language of Its Own restores music to its rightful place in the history of ideas.
