Zeynep Bulut is currently a postdoctoral research fellow at the ICI Berlin Institute for Cultural Inquiry. She received her Ph.D. in Critical Studies/Experimental Practices in Music from the University of California at San Diego in 2011. Prior to her doctoral education, she studied sociology (B.A.), opera, and visual arts (M.A.) in Istanbul, Turkey. Zeynep investigates the use of non-linguistic voice and bodily sounds in experimental music and sonic arts, drawing on psychoanalysis, phenomenology, and sound and performance studies. In light of this research, and inspired by French psychoanalyst Didier Anzieu’s notion of skin-ego, she theorizes voice as skin, as a physical and phenomenal matrix of senses, a primary point of contact and difference between self and the external world. Her broader research interests include historical epistemologies of hearing, anthropology of senses and affect, deaf performance and culture, and voice and speech disorders in the history of science and medicine. She is currently working on her book, entitled Skin-Voice: Contemporary Music Between Speech and Language. In addition, she is writing two articles, one for the forthcoming volume Gestures of Music Theatre: The Performativity of Song and Dance (Oxford: Oxford University Press), and another for the academic journal Musica Humana (Seoul, Korea). Her most recent publication, “Theorizing Voice in Performance: György Ligeti’s Aventures,” appeared in Perspectives of New Music. Alongside her scholarly work, Zeynep has also composed and performed voice and sound pieces for concert, video, and theatre, which have been exhibited in the United States, Europe and Turkey.
