This piece war produced at Institute for Electroacoustic, Experimental and Applied Music in Vienna/Austria,  Institute of Electronic Music in Graz/Austria and at Atelier Avant in Graz/Austria

The improvised melody in this piece is basically displayed with 7 church-modes.
the cat and the mouse is computer-aided composition in which Freezing, Modulation, Filtering and Granular-Synthesis are used to complete the sound processing.
The reason for the cat and the mouse to be challenging and gripping is because it's a interactive Real-Time play-game between guitar, piano and the computer.When the musicians are playing, the computer records the sounds in real-time, process the recording sounds, and store it up. The musicians release then the stored sounds through the computer by improvising on instrumens. Involvement, intertwining and interlocking flow into this performing stage.

Communication in varied layers

1. The improvisation as a limpid communication between the musicians (guitar/piano)

2. The stream of informations in the main computer by Soundprocessing (ISPW)

3. concealed communication between the musicians, the computer and among surroundings (Laptops)
The Laptops send off the digital operation commands from the Interpretist on the main computer (ISPW) and carry out the exchange of the informations amongst.
