The light quartet Die Zusammensetzung der Welt penetrates into the depths of our existence – which is a realm of incredible beauty. And be aware: the further you dig, the more of that beauty reveals itself. The work explores this depth by means of prepared light microscopes, which uncover samples of various inorganic and organic substances and send their discoveries to TVs and projectors, while the viewers themselves become a screen and immerse themselves in the work. The sound increasingly delves into the background, but at the same time also into the substance of the world. The listener sinks into the depths of the ocean, climbs up to the heights of winds, listens to the silence of the grave and burns in a roaring fire. In addition, the actions of the players (during an installation: of the audience) are inspected by means of contact microphones. However, the focus is on the visual level, which – like all sounds – completely ascends from the art of the notation and thus can be perceived in two ways. During the performance, however, the players do not work with the score. They receive their instructions from the conductors and the light tubes underneath the table, which emit polarised as well as unpolarised light of various kinds and enables them to access the samples in always different manners.
