state space has been developed for the project "Quantum Music: Hannover Session" and was presented in February 2019 at the Calder hall of the Sprengel Museum Hannover.
"Quantum Music: Hannover Session" was organized by URWERK e.V. Hannover
in cooperation with Sprengel Museum and Musik 21 Niedersachsen.
Accordion: Snežana Nešic
The installation state space has been inspired by some phenomena of quantum mechanics: the superposition of different states (positions, velocites) of a system, the entanglement of particles, the wave function collapse through observation ...
The visitors enter an instable audio-visual system which changes its states depending on the presence of people at the hall. Everything that is happening there is projected back as a time sequence folded into space. The superposition of all acoustic states is equivalent to the accordion playing of Snežana Nešic.
A webcam captures the moving visitors in the hall. The camera picture is projected to the space but deferred by different delay times (slit-scan). At the same time the camera is also used for a motion detection, which triggers changes in the sound. An accordion recording is filtered by very narrow bandpasses whose center frequencies are changed to new random values on the occurence of motion in the space.
The programming of the video processing was done with openFrameworks whereas all sound treatments were realized with SuperCollder.
