This interdisciplinary study focuses on sonic poetry, an experimental artistic practice in the post-digital era. It discusses a transmedial, language-based sound art, according to literary concepts, as well as media theory, linguistics, and sound studies. The book explores how digital and media technologies shape the creation of experimental sound works. Offering a framework, it categorizes the large variety of production methods applied by artists, such as editing, mixing, sampling, and coding. Drawing on literary concepts like electroacoustic poetry or audioliterary writing, it introduces a theory of expanded semantics to analyze the intricate interplay between sound and meaning. Four in-depth case studies of works by Alessandro Bosetti, Dagmara Kraus, Jörg Piringer, and Anja Utler, reveal how artists engage in a dynamic and reciprocal relationship with technology – transforming it from a mere tool into an active collaborator in the creative process. This book aims to fill a gap by reconstructing the evolution of poetry related to sound, media, and technology. Providing compelling insights into the innovative tendencies of artistic production, it also sheds light on issues of culture and society in the twenty-first century.
