Copia – a sound installation for historic keyboard instruments and 20 loudspeakers by Oliver Wiener and gksh
At the Institute of Music Research University of Wuerzburg: Study-collection of musical instruments.
For the sound installation Copia, resonances were recorded from a group of historical instruments and processed with various software tools and filters.


What happens when the recorded sound, separated from its source, is altered in the computer and then – in the vicinity of it´s source  – is made audible again?

In contrast to many other sound art works, here – sound is not decontextualised or “robbed” of its origin and treated as “concrete” music, it also does not emerge – after a chain of alterations as something quite different (e.g. a sound object)  in order to be spatialized. We hear sounds in Copia, those of the visible instruments. Sometimes the sounds are more familiar – e.g. they are assignable to the sound generator – sometimes they seem alien, then they have (apparently) nothing in common with their source. In this distance between familiar and strange, possible and impossible, played and processed – the work wants to play with the auditory experience of the visitor.

Sound Sculpture

Working in the fied of so called “spatialized music” for about 15 years I was asking myself how to describe the phenomena I was producing in loudspeaker environments better, – in other words – how to find descriptions and techniques that are knowledge- and perception-based at the same time? The aim is to find a […]

Eadweard’s Ear – Muybridge extended

Eadweard’s Ear-Muybridge extended – an interface for composers, dancers and musicians. The dancers’ movements are transformed in real time into a graphical notation by a specially developed interface. The generated movement data are interpreted by musicians on the basis of a trained compositional structure. In turn, they evoke the immediately resulting movements of the dancers.  […]
