What characterises the sound identity of a city? What defines its most iconic soundscapes? How can these soundscapes be mixed, intertwined and played into creating a living, dynamic portrait of a city? Planar is a multimodal portrait of the Portuguese city of Coimbra, interpreted through an audiovisual installation for the visitors to uncover and experience a new perspective of this city. The audiovisual composition emerges through an aerial view, with an abstract representation of its streets and paths in an evolving representation of the standard city map. Insect-like beings serve as intelligent, living paintbrushes who uncover those monochromatic streets, alongside the blue river that runs across the city. Bird-like beings wander above these streets, travelling together in a swarm that randomly weaves its journey through the map. Their passage unveils the city’ sounding places, becoming narrators of sonic fragments in an ephemeral composition that depicts the main soundscapes of Coimbra.
