The Integrated Soundscapes of Byzantium: Ritual and Musical Coherence across Performance Frameworks until Hesychasm

This paper proposes a holistic, interdisciplinary rethinking of Byzantine sonic culture, mapping its unified performative soundscape that deeply integrated palatial, liturgical and public spaces until the Hesychast era (14th century). Despite diverse performative frameworks (urban churches, imperial palace, Hippodrome, and streets), shared musical and ritual structures and practices fostered a cohesive performative culture. These structures, encompassing chant, gesture, movement and spatial dynamics, shaped communal life and practice, profoundly bridging sacred and civic domains. Among others, key examples illustrate this interconnected framework: The Trinitarian hymn (Trisagion) resounded in sanctuaries, streets, and the Hippodrome, establishing a shared theological-musical language. Antiphons and stichera were adapted for imperial ceremonies, blurring liturgical and courtly protocols. Also, the hymn Who is So Great a God as Our God used for the Vespers of the Genuflexion was repurposed for the Emperor’s triumphant return and the public submission of foreign chiefs, while antiphonal chants concluding with a polychronion in the Hippodrome followed the structure of ecclesiastical stichera. Drawing on musical manuscripts, liturgical typika, iconography, and historical narratives, this study reveals a dynamic, fluid performative system. However, the Hesychast era marked a decisive shift toward exclusion, fragmentation, and an introspective approach to chanting: the laity was separated from viewing the sanctuary, children were removed from civic monastic schools, and women’s chants were increasingly silenced in urban churches. The clerical appropriation of the Akathistos Hymn and the prohibition against the participation of Constantinopolitan monks in the liturgical celebrations of Hagia Sophia, ratified by patriarchal decree in a foundation document, exemplifies this narrowing. By tracing these transformations, this paper argues that Byzantine performance culture was a deeply integrated system, where public, imperial, and spiritual dimensions were mutually constitutive, until later reforms fragmented this shared sonic space.
