The Schumann Resonance, 1999, Gallery Shuppenhauer, Cologne, Germany

The Schumann ResonanceIn collaboration with Ragna Robertsdottir 
This phenomenon is one of the naturally occurring magnetic fields that have always surrounded us. It appears that the space between the earth’s surface and the ionosphere forms a gigantic resonant cavity with physical dimensions that give it a frequency somewhere between 7hz and 8hz, 7,83 to be exact. Producing two tones 60hz and 52,2hz you get an interference wave of 7,8hz
