The Artsoundscapes Project participated in the “Festa de la Ciència” [Science Fair] of the University of Barcelona (UB) on 17 May 2019. The event is organized yearly within the “La UB divulga” programme, led by the Unitat de Cultura Científica i Innovació at the UB. The project was represented by team members Laura Coltofean-Arizancu, Ana María Alarcón-Jiménez and Mathieu Picas, who organized the workshop “Viaje sonoro a la prehistoria” [Sonorous voyage to prehistory]. They talked about rock art, sound and musical instruments in prehistory with children, teenagers and adults. At the end of the workshop, they taught the participants to build two prehistoric percussion and wind instruments: “chascas de nuez” (a nutshell musical instrument) and bullroarers.
