The acoustic part of the sound sculpture was constructed by the Munich-based organ builder Markus Harder-Völkmann. Although the ensemble of free-standing pipes looks rather unorthodox, the technology used to manufacture it adheres to traditional organ-building methods. The sophisticated electro-pneumatic valves are built to withstand years of continuous use in the extremely variable climatic conditions of the unisolated metal structure.
