The communication of intangible heritage, especially for the contemporary repertoire, is a hard challenge. Interactive narratives can address this challenge by integrating the stories told by media scholars with physical and virtual engagement devices that display stylistic, cultural, and performative dimensions. In this context, contemporary music is particularly challenging, because of its opening to non-traditional sound timbres, spatial arrangement of the performance, and multimodality of experience. This paper introduces the mixed-reality serious game Edgar à GoGo, designed to foster post-listening engagement and enable players to explore both the sound components and their sequencing within an electroacoustic piece. The piece is a paradigmatic composition of Edgard Varèse, the Poème Électronique (1958), a landmark of electroacoustic music originally conceived for the Philips Pavilion at the Brussels World's Fair. This piece was a component of the multimedia show conceived by Le Corbusier, with the collaboration of Iannis Xenakis, to display the potentials of Philips technology at the time. The game has been developed in a virtual prototype and has been evaluated by experts, whose comments have been taken into account for the definitive design, including physical twins that will embody material affordances for anchoring the intangible heritage. The narrative is experiential and non-linear, unfolding through discovery, manipulation, and recomposition of sound objects, echoing the creative principles of musique concrète.
