The loudspeaker configuration is made up of three components:

1 an outer circle consisting of 15 loudspeakers starting at the right edge of the stage and finishing at the left edge of the stage. The loudspeakers are positioned at a successively increasing, then again succesively decreasing height.

2 Two columns consisting of 4 loudspeakers each, which oppose each other in the inner space. Here, the heights of the loudspeakers are staggered.

3. Four aura loudspeaker boxes, which have been placed in each corner of the room. This group of loudspeakers provides an acoustic ground in the room, transmitting the bass frequencies.

The computer-controlled grand piano is present on the stage. It is synchronized by a computer with the loudspeaker configuration. In the performance, a Bösendorfer computer-controlled grand piano is used.
