Book excerpt: Icons of Sound: Voice, Architecture, and Imagination in Medieval Art brings together art history and sound studies to offer new perspectives on medieval churches and cathedrals as spaces where the perception of the visual is inherently shaped by sound. The chapters encompass a wide geographic and historical range, from the fifth to the fifteenth century, and from Armenia and Byzantium to Venice, Rome, and Santiago de Compostela. Contributors offer nuanced explorations of the intangible sonic aura produced in these places by the ritual music and harness the use of digital technology to reconstruct historical aural environments. Rooted in a decade-long interdisciplinary research project at Stanford University, Icons of Sound expands our understanding of the inherently intertwined relationship between medieval chant and liturgy, the acoustics of architectural spaces, and their visual aesthetics. Together, the contributors provide insights that are relevant across art history, sound studies, musicology, and medieval studies.
