»Zeichen der Nacht, vers. 1«
for organ with mechanical stop action & electronic
The soundperformance »Zeichen der Nacht« used the sounds of wind, pure overtones and self-oscillating organ-pipes which come to life when you operate the stops of a mechanical organ the analog way: pulling them out only bit by bit – producing infinite cascades of overtones.
The figurations and tonal clusters of the organ part were derived from star constellations: signs of night.
