Book Description

Thinking with Sound traces the formation of auditory knowledge in the sciences and humanities in the decades around 1900. When the outside world is silent, all sorts of sounds often come to mind: inner voices, snippets of past conversations, imaginary debates, beloved and unloved melodies. What should we make of such sonic companions? Thinking with Sound investigates a period when these and other newly perceived aural phenomena prompted a far-reaching debate. Through case studies from Paris, Vienna, and Berlin, Viktoria Tkaczyk shows that the identification of the auditory cortex in late nineteenth-century neuroanatomy affected numerous academic disciplines across the sciences and humanities. “Thinking with sound” allowed scholars and scientists to bridge the gaps between theoretical and practical knowledge, and between academia and the social, aesthetic, and industrial domains. As new recording technologies prompted new scientific questions, new auditory knowledge found application in industry and the broad aesthetic realm. Through these conjunctions, Thinking with Sound offers a deeper understanding of today’s second “acoustic turn” in science and scholarship.

Book Description

Analyzes audio recordings of interwar Hebrew plays, providing a new model for the use of sound in theater studies. Possessed Voices tells the intriguing story of a largely unknown collection of audio recordings, a valuable tool for understanding historical theater, which preserve performances of modernist interwar Hebrew plays. Seldom used in scholarship, Ruthie Abeliovich focuses on four recordings: a 1931 recording of The Eternal Jew (1919), a 1965 recording of The Dybbuk (1922), a 1961 radio play of The Golem (1925), and a 1952 radio play of Yaakov and Rachel (1928). Abeliovich traces the spoken language of modernist Hebrew theater as grounded in multiple modalities of expressive practices, including spoken Hebrew, Jewish liturgical sensibilities supplemented by Yiddish intonation and other vernacular accents, and in relation to prevalent theatrical forms. The book shows how these performances provided Jewish immigrants from Europe with a venue for lamenting the decline of their home communities and for connecting their memories to the present. Analyzing sonic material against the backdrop of its artistic, cultural, and ideological contexts, Abeliovich develops a critical framework for the study of sound as a discipline in its own right in theater scholarship. “The author’s focus on historicizing and analyzing sound recordings and radio plays as a means to tackle the pervasive ephemerality problem in theater studies is a novel and valuable approach that represents a significant intervention in the field. These types of sources have had scant attention in theater studies to date, but Abeliovich makes a compelling argument that they belong at the center.” — Debra Caplan, author of Yiddish Empire: The Vilna Troupe, Jewish Theater, and the Art of Itinerancy

Book Description

Choral Voices: Ethnographic Imaginations of Sound and Sacrality is about sacred and secular choirs in Goa and Shillong across churches, seminaries, schools, auditoriums, classrooms, reality TV shows, and festivals. Voice and genre emerge as social objects annotated by tradition, nostalgia, and innovation. Piety literally and metaphorically shapes the Christian lifeworld, predominantly those belonging to the Presbyterian and Catholic denominations. Indigeneity structures the political and cultural motifs in the making of the Christian musical traditions. Located at the intersection of Sociology, Anthropology, and Ethnomusicology, the choral voices emplace 'affect' and the visual-aural dispatch. Thus, sonic spectrum holds space for indigenous and global musicality. This ethnographic work will be useful for scholars researching music and sound studies, religious studies, cultural anthropology, and sociology of India.

Book Description

In the motets of Philippe de Vitry, Guillaume de Machaut, and their contemporaries, tenors have often been characterized as the primary shaping forces, prior in conception as well as in construction to the upper voices. Tenors are shaped by the interaction of talea and color, medieval terms now used to refer to the independent repetition of rhythms and pitches, respectively. The presence in the upper voices of the periodically repeating rhythmic patterns, often referred to as "isorhythm," has been characterized as an amplification of tenor structure. But a fresh look at the medieval treatises suggests a revised analytical vocabulary: for many fourteenth- and fifteenth-century writers, both color and talea involved rhythmic repetition, the latter in the upper voices specifically. And attention to upper-voice taleae independently of tenor structures brings renewed emphasis to the significant portion of the repertory in which upper voices evince formal schemes that differ from those in the tenors. These structures in turn suggest a revision of the presumed compositional process for motets, implying that in some cases upper-voice text and forms may have preceded the selection and organization of tenors. Such revisions have implications for hermeneutic endeavors, since not only the forms of motet voices but the meanings of their texts change, depending on whether analysis proceeds from the tenor up, or from the top down. Where the presumed compositional and structural primacy afforded to tenors has encouraged a strand of interpretation that reads the upper-voice poetry as conforming to, and amplifying, the tenor text snippets and their liturgical contexts, a "bottom-down" view casts tenors in a supporting role and reveals the poetic impulse of the upper voices as the organizing principle of motets.

Book Description

Why do so many contemporary British novels revert to the Victorian tradition in order to find a new source of inspiration? What does it mean from an ideological point of view to build a modern form of art by resurrecting and recycling an art of the past? From a formal point of view what are the aesthetic priorities established by these postmodernist novels? Those are the main questions tackled by this study intended for anybody interested in the aesthetic and ideological evolution of very recent fiction. What this analysis ultimately proposes is a reevaluation and a redefinition of postmodernism such as it is illustrated by the British novels which paradoxically both praise and mock, honour and debunk, imitate and subvert their Victorian models. Unashamedly opportunistic and deliberately exploiting the spirit of the time, this late form of postmodernism cannibalizes and reshapes not only Victorianism but all the other previous aesthetic movements - including early postmodernism.

Book Description

An award-winning study of how formal and informal public discourse shapes opinions A foundational text of twenty-first-century rhetorical studies, Vernacular Voices addresses the role of citizen voices in steering a democracy through an examination of the rhetoric of publics. Gerard A. Hauser maintains that the interaction between everyday and official discourse discloses how active members of a complex society discover and clarify their shared interests and engage in exchanges that shape their opinions on issues of common interest. In the two decades since Vernacular Voices was first published, much has changed: in the aftermath of the 9/11 terrorist attacks, US presidents have increasingly taken unilateral power to act; the internet and new media have blossomed; and globalization has raised challenges to the autonomy of nation states. In a new preface, Hauser shows how, in an era of shared, global crises, we understand publics, how public spheres form and function, and the possibilities for vernacular expressions of public opinion lie at the core of lived democracy. A foreword is provided by Phaedra C. Pezzullo, associate professor of communication at the University of Colorado Boulder.
