MUSIC, ANALYSIS, AND THE BODY: EXPERIMENTS,
EXPLORATIONS, AND EMBODIMENTS
Series:
Analysis in Context. Leuven Studies in Musicology, 6
Editors: Thumpston R., Reyland N.
Summary:
How do our embodied experiences of music shape our analysis,
theorizing, and interpretation of musical texts, and our engagement with
practices including composing, improvising, listening, and performing?
Music, Analysis, and the Body: Experiments, Explorations, and Embodiments is a
pioneering and timely essay collection uniting major and emerging scholars
to consider how theory and analysis address music’s literal and figurative
bodies. The essayists offer critical overviews of different theoretical
approaches to music analysis and embodiment, then test and demonstrate
their ideas in specific repertoires. The range of musics analysed is diverse:
Western art music sits alongside non-Western repertoires, folk songs, jazz,
sound art, audio-visual improvisations, soundtracks, sing-alongs, live
events, popular songs, and the musical analysis of non-musical
experiences. Topics examined include affect, agency, energetics, feel,
gesture, metaphor, mimesis, rehearsal, subjectivity, and the objects of
music analysis – as well as acoustic ecology, alterity, class, distraction,
excess, political authority, sensoriality, technology, and transcendence.

ANALYSIS IN CONTEXT. LEUVEN STUDIES IN MUSICOLOGY
This peer-reviewed series aims at consolidating recent trends in music analysis in which
analytical and historical research are seen as interdependent. Compositions will not be
analysed in order to prove the validity or propose the universality of any particular theory
but rather to disclose their specificity within the historical context in which they originated.
This approach may include aesthetic ideas, compositional and listening strategies, sociological conditions, theoretical systems, or genre conventions. Consequently, the aims,
methods and results of analysis may be as widely divergent as music history is (historical research as a tool of analysis). On the other hand, if musicology is to include the
study of musical works of art, a contextual analysis of compositions is indispensable
(analysis as a tool of historical research). Analysis in Context is addressed to an international readership.
