Prof. Caspar Stracke
with Marianne Decoster-Taivalkoski, Eero Pulkkinen, Jonas Olesen
May 27th – May 31th. 2013, KUVA Helsinki, Finland
The second Helsinki module of the 2012/13 Nordic Sound Art cycle will include a lecture and workshop and investigate various aspects of the notion of reverberation, defined as both, an acoustical phenomenon and a conceptual strategy in sound art.
We will research on specific projects by Max Neuhaus, Phill Niblock and listen / discuss various case studies by Andy Graydon, Richart Garet and Helsinki sound artist Eero Pulkkinen.
The workshop part will take place in the main water reservoir tank of an abandoned watertower in Lautasaari. This site will serve as a sound installation test site (and optional; recording site) not only for experiments with natural reverberation but also as an project idea incubator for site specific exercises. A specific space to attach a sound to and then also respond to the physical location by simple visual and sculptural means.
NSA participants will produce, playback and re-record and sound sources, place them in a specific locations and work with various sculptural / visual elements to create relationships between the sound source, reverberation and environment.
Reverberation and resonant bodies
Reverberation is the result of sound propagation in an environment with reflective surface. When a sound is performed in a space, part of the energy of the sound wave is absorbed and part is reflected back and propagated until the wave hits another reflective surface.
Reverberation plays an essential role in our perception of a space. Reverberation informs the listener not only on the sound source but also on the environment, on the physical quality of a space, like its size, its shape, its materials. Acoustic spaces have their own behaviours and acoustic characteristics. Acoustic spaces can be considered as potential meta-instruments. They have their own resonant frequency. They transform or filter original sound sources that we perform or play inside them. Sound artists think of reverberating spaces as resonators, performance venues or recording studios.
Marianne Decoster-Taivalkoski (born in France in 1969), media & sound artist based in Helsinki, is currently lecturer in Media and Sonic Arts at the Centre for music and technology in Sibelius Academy, University of the Arts Helsinki.
Her work includes motion sensitive interactive sound installations and electroacoustic soundscape performances based on improvisation. Working with water sounds (live or recorded) and the poetics of water and fluids has been a recurrent theme in her pieces.
