Gustav Mahler’s anniversary years (2010–11) have provided an opportunity to rethink the composer’s position within the musical, cultural and multi-disciplinary landscapes of the twenty-first century, as well as to reassess his relationship with the historical traditions of his own time. Comprising a collection of essays by leading and emerging scholars in the field, Rethinking Mahler in part counterbalances common scholarly assumptions and preferences which predominantly configure Mahler as proto-modernist, with hitherto somewhat neglected consideration of his debt to, and his re-imagining of, the legacies of his own historical past. It reassesses his engagement both with the immediate creative and cultural present of the late nineteenth century, and with the weight of a creative and cultural past that was the inheritance of artists living and working at that time. From a variety of disciplinary perspectives the contributors pursue ideas of nostalgia, historicism and ‘pastness’ in relation to an emergent pluralist modernity and subsequent musical-cultural developments. Mahler’s relationship with music, media and ideas past, present, and future is explored in three themed sections, addressing among them issues in structural analysis; cultural contexts; aesthetics; reception; performance, genres of stage, screen and literature; history/historiography; and temporal experience.
