"JazzTube" is a sound installation initially created by Foton for the .Motives Jazz festival 2005 and the city of Genk. Jazz is music - music is sound - sound is waves. Making these waves visible to the naked eye is what "JazzTube" is about. "JazzTube" is part composition, part hardware. The composition is a fragmented collage, reshaping sound snippets from the artists who performed during the .Motives festival. The hardware consists of two metal tubes with built-in speakers, positioned above the water of a fountain. Sound waves travel from the speaker through the tubes, onto the water surface. Sound becomes visible.

"JazzTube" can be reconfigured into a more generic "SoundTube" for all different kinds of music and compositions, and can be extended by adding more tubes.
