The “Folldal Åpen Form Paviljong av Luft” (Folldal Open Form Pavilion of Air) is a floating roof of sound across the front of the Helsestien Viewpoint in Foldlal, triggered by GPS and accessed via a smartphone, headphones and the echoes.xyz app. Inspired by Polish architects Oskar & Zofia Hansen’s “Open Form” architectural concept (ca. 1959), this audiowork is one of 15 locations in 9 countries in the pan-European Open Form Pavilion of Air series, using sound and site-mapping to offer a playful renewal and reframing of public space as an essential place of engagement for the community.

By walking through different zones at the front of the Helsestien Viewpoint,while using your mobile phone, the Echoes app and headphones, you become a participatory listener producing a composition in real-time. Your navigation creates a unique choreography via GPS, combining and changing sounds mapped along the viewpoint through the app. Hear this unique mountainside location and its context become transformed by the sounds forming this floating acoustic architecture, revealing an immersive, profoundly spatial and physical experience. The Pavilion has no visible presence outside the app and can only be accessed and enjoyed at the Helsestien Viewpoint in Folldal.
