The multidisciplinary art project Centre of sounds, margin of silence opens a new chapter of international cooperation, exploring the sonic landscapes of city spaces, their gravitational zones and periphery through urban centres in Croatia, Switzerland and Columbia: Zagreb, Zadar, Zurich, Santa Marta and Bogota. By soundmapping the daily life of urban centres, we aim to bring a local, familiar environment and a foreign, unfamiliar one into a hitherto unexplored comparative relation, explore their convergence and divergence points, and open the possibility of new ways of understanding, since these cities have significantly different tactics of urban planning.
