(The Log Sonata)

Two Logs. One Grand Piano. A Computer. 16 speakers. A remarkebly simple setup with a completely uncontrolled output.

The Grand Piano is placed in the middle of a circle of speakers. The audience is sitting around the Grand Piano with the speakers in their back. The player can only play with the two logs. One log is covering the white, one is covering the black keys.
There are four options: All the whites. Alle the blacks. All the whites and all the blacks together. Silence.

This is piece is inspired by two concepts:
1. The sound is inspired by the piano hall in the Bösendorfer factory in Vienna where Grand Pianos are prepared. Big machines are pressing down all the keys at once. At 20 Grand Pianos.
2. The technique is inspired by finding the computer as being a very, very slow interface compared to the piano.
"In the Log Sonata I am trying to build an instrument which is like syrup, very slow and non-interactive. I also want the public to be inside the instrument. The speakers are surrounding them, placing the piano in the middle of a circle. It is like being inside a very slow moving instrument."

This is a piece built for a room, not possible to reproduce in stereo, but nevertheless, here is a short excerpt of one version:
