De Atsunobu Kohira installation 2009
Speak down underground and feel the earth. the voice plunges beneath the ground, the body remains on the surface. Infravoice is a sound-producing instrument inspired by my experience of earthquakes in Japan and concerns the relationship between man and the earth. the instrument makes it possible to modulate the voice and attain sound frequencies equivalent to those of an earthquake. the focus is buried deep vertically beneath the position of the microphone so that the voice "tremor" can propagate downwards into the ground. the phenomenon of feeling its vibration on the surface reveals an echo which rises from the earth.
