Architecture forms all sounds we hear. Urban architecture is a sound box, it shapes a space, wherein the range of sounds that surround us is resounded and reflected. In the video “Stadtmusik”, the Linz-based media artist Dietmar Offenhuber and the Berlin formation TamTam (San Auinger / Hannes Strobl) deal with sound in cities, by analysing sound structures which are triggered by urban buildings and facilities. They focus on the aspect of movement in the city, which reinforces a dynamic experience of the urban soundscape: particular sounds emerge through movement, sound and its timbre evolves from material and space.
