Invisible Sounds
A ‘stethoscope’ towards sounds unheard

Concept and composition: Anders Hultqvist och Stefan Östersjö
Guitar - Stefan Östersjö
Sound system and programing - Per Sjösten

With the use of Fishing lines, a hydrophone, a guitar, ground vibrations and the solar wind we will try to capture and make visible some of the environmental sounds that affects our daily living milieu, and this largely without us actively noticing them.

The prolonged strings (7meters) mounted on the guitar captures tonal movements in the wind, while the hydrophone can enlarge the sound milieu mostly hidden in the river. The ground vibrations caused by traffic is there as well as the solar wind by which important parts of our electromagnetic environment is created. (All together this adds up to something that can be seen as a sounding content of what could be summed up in the concept of the four elements - Earth, Water, Air and Fire, or as they might be labelled today: Solid, Liquid, Gas and Plasma.)

The technical set-up of the installation allows us to record these sounds but the live-mixing of the sound sources is essential here. The installation is built on a concept of participation. The guitarist Stefan Östersjö is interacting with the installation through playing, using different techniques, on the aeolian guitar.
