Sky Brought Down is a 16-channel real-time-controlled sonification of the sky outside Sahlgrenska University Hospital, Gothenburg, Sweden.
Commissioner: Konstenheten, Västra Götalandsregionen (in English, the Arts Division of Region Västra Götaland).
Curator: Brita Bahlenberg.
Software developer: Andre Bartetzki.
Technical concept and realization: Manfred Fox.
Sky Brought Down was developed for a new indoor atrium and main staircase at the Center for Imaging and Intervention at Sahlgrens¬ka University Hospital, where a glass ceiling allows a visual direct contact with the sky, which is subsequently sonified in the building through the work.
The work takes as its conceptual foundation the sky outside the hospital. A weather station on the roof of the hospital forwards weath¬er data in real time to the sound installation. This data is transformed into different types of sound textures. Low pressure systems, high pressure systems, precipitation, wind speed, wind pressure, and light all generate different sorts of sonic expressions in real time, according to a complex structure of algorithms. A total of 16 speakers, which are mounted behind the wooden panelling that runs through the atrium from floor to ceiling, provide for a vertical listening experience.
The work was part of Stjerna's dissertation in artistic research: Before Sound—Transversal Processes in Site-Specific Practice, (2018) University of Gothenburg.
