The Cambridge History of Twentieth-Century Music? What sort of a history of twentieth-century music might that be? The word ‘Cambridge’ is something more than a publisher’s imprint, for it locates this volume in a century-long tradition of Cambridge Histories and so emphasizes that this first large-scale, retrospective view of the twentieth century in music is a view from somewhere. As the title would lead you to expect, it is history written from a distinct and relatively homogeneous geographical, social, and cultural perspective: predominantly Anglo-American (though there are two authors from Germany and one each from South Africa and Australia), more male than female (gender representation in musicology, at least in the UK, remains far from equal), and white. That does not, of course, mean that our authors simply accept the traditional geographical, ethnic, and gender hierarchies of music history, for there is a strong revisionist strain in the book, one that attempts to contextualize and critique familiar narratives by juxtaposing them with alternative constructions of twentieth-century music. Like all historical writing, this Cambridge History is best understood as in essence a status report, a series of position statements in an ongoing dialogue, for no history can be more than a temporary stopping-point in a never-ending process of interpretation – which means that history is less a reflection of the facts than a construction of historians. What follows, then, is one particular set of constructions, the record of what a particular group of authors thought at a particular point in time.
