Rediscovering the Intangible Heritage of Past Performative Spaces: Interaction between Acoustics, Performance, and Architecture

The relationship between the shape and social use of Greek and Roman theatres has always been overshadowed by the technical and acoustic analyses of these performance spaces. Relevant ruins illustrate the relationship between performance typology, acoustics, and construction development of ancient theatres, which were mainly determined by the requirements of artistic venues. The music in tragedies and comedies, the dances, and the public speeches performed in the same places helped to shape the constructions according to the requirements of the events. In addition to the need to satisfy social and political interactions, the functions of musical performances and public speeches in theatres were maintained across generations so that they organically coexisted in both Greek and Roman times. This paper presents new insights into the relationships between sound and architecture, focusing on the case study of the Greek–Roman theatre of Katane and its evolution through the centuries. Architectural features have been described in terms of the social functions of the theatre rather than as mere results of geometric rules. A brief comparison with the neighboring odeion of Katane and other Greek–Roman theatres has been made regarding destination use
