Ernst Schering Foundation - Berlin

Four automated aerial drones make up the sound installation TETRAKTYS, which the Berlin-based artist Jens Brand developed specifically for the Project Space of the Ernst Schering FoundationTETRAKTYS refers to the Music of the Spheres, which is based on the ancient idea that the movement of celestial bodies generates sounds that produce a harmony.

The Pythagorean “harmony of the spheres” and resulting notions of the “musica mundana” (Boethius) and “harmonice mundi” (Johannes Kepler) once served as a universal model for explaining the order of the cosmos. The ideas of a world based on simple numerical proportions and of the unity of art and science continued to fascinate people until well into the modern era. TETRAKTYS plays with these interpretive contexts in subtle and ironic ways.

Brand’s humming model of the spheres is generated with the aid of devices that are normally employed in entirely different contexts. The aerial drones, which form the corners of a virtual tetrahedron in space, function as sound generators of a mechanical model of the sky. Their simple chord structures, based on fifths, create changing sound surfaces that, as humming “spheres,” accompany the continually changing spatial constellations of the “celestial bodies.”


TETRAKTYS is part of a Jens Brand’s series of experiments with “world machines” — artistic and scientific models designed to challenge aspects of reality and to explain cosmological phenomena. Brand sees his devices and installations such as G-Player (2004), Small World Machine (2011) or Space/Site Work II (2013) as distinctive metaphors about the appropriation of space through sound or of sound through its spatial context. The installation TETRAKTYS, too, investigates this tension, going far back into the history of art and science.

TETRAKTYS is part of “resonating spaces,” a series of events organized by singuhr—projekte that investigates the topic of “space and sound” from a variety of artistic perspectives. At the same time, the exhibition is a satellite project of the group show entre límites / zwischen grenzen organized by singuhr—projekte at Kunstraum Kreuzberg / Bethanien and featuring new sound installations by a total of ten Mexican and German artists.


Jens Brand

Jens Brand (born 1968 in Dortmund) studied fine arts at the Münster Academy of Fine Arts (1988–94). Inspired by Phill Niblock and the artistic environment at Paul Panhuysen’s Het Apollohuis, he turned to experimental music and sound art. Since then, he has created a large number of installations, music performances, and cross-media works. In 1992, he began an intensive collaboration with Waldo Riedl and founded mex e.V., an initiative to promote cross-media and experimental music and media projects. Jens Brand has been awarded, among many others, with a Siemens Project Fellowship for his computer installation Affen (Apes, 1998) and has received many commissions to create compositions. He was a fellow at Villa Aurora in Los Angeles in 2003 and taught at the Münster Academy of Fine Arts in 2004. He is a member of the German Arts Council and of the Media Expert Committee of the German Culture Council. Since 2013, he has been a professor at the Kunsthochschule Kassel. Jens Brand has lived and worked in Berlin since 2010.
