We will open an interactive installation at the Ultima Contemporary Music Festival in Oslo tomorrow, featuring 6 guitars, each with a Bela.
Stand still. Listen. Locate the sound. Move. Stand still. Listen. Hear the tension. Feel your movements. Relax. Stand stiller. Listen deeper. Feel the boundary between the known and the unknown, the controllable and the uncontrollable. How does the body meet the sound? How does the sound meet the body? What do you hear?
The technical setup of Sverm-Resonans is focused on the meeting point between digital and acoustic sound making. Each of the guitars is equipped with a Bela micro-computer, which produces electronic sound through an actuator placed on the back of the guitars. There are no external speakers, all the sound generation is coming the vibration of the acoustic guitar. Each of the guitars produce a slowly pulsing sound - based on an additive synthesis with a slight randomness on the sine tones - that breathes and gives life to the soundscape. The guitars are also equipped with an infrared sensor that detects the presence of a person standing in front of the guitar, and which inversely controls the amplitude of a pulsating noise signal. That is, the longer you stand still, the more sound you will get.
About the installation
Sverm-Resonans is a new sound installation by Alexander Refsum Jensenius, Kari Anne Vadstensvik Bjerkestrand, Victoria Johnson, Victor Gonzalez Sanchez, Agata Zelechowska, and Charles Martin. The installation is the result of the ongoing art/science research projects Sverm, MICRO and AAAI, three projects which in different ways explore human micromotion and musical microsound. Supported by University of Oslo, Research Council of Norway, Arts Council Norway, The Fund for Performing Artists, The Audio and Visual Fund, and The Nordic Culture Fund.
