SONAR “Microtonal Wall” by Tristan Perich

Microtonal Wall is an installation consisting of 1,500 loudspeakers on a 7.5-metre aluminium panel. Each speaker emits one single sound, the result of dividing six octaves into microtones in a continuum of individual frequencies.
Listeners spatially experience the transition from white noise to tone as they approach the work and, in the last instance, to the resolution of a single tone when they place their ear to one of the speakers. This work explores the finite limits of the digital media and alludes to the infinite through a repeated structure.
Microtonal Wall, which was originally commissioned by Rizoma, has been presented at the New Museum, at the Lydgalleriet for the Ekko Festival in Bergen, Norway, and later at the Museum of Modern Art, New York, as well as at InterAccess in Toronto. Now, as part of Sonar, we may appreciate the way it interacts with the Mies van der Rohe Pavilion. Perich’s work continues a series of pieces exhibited in the same space over the past years by artists such as Francisco López, Edwin van der Heide and Álex Arteaga, all of them curated by Lluís Nacenta.
