Schwarzwald is a sound installation based on voice recordings on magnetic tape imitating animal sounds. It associates playfully with the ability and inability of capturing and miming nature sounds with the human voice through a kinetic arrangement. Schwarzwald tries to capture, the qualities and characteristics of the sounds on a very individual and abstract level. The start, stop, speed and therefore pitch of the magnetic tape, as also the forward or backward direction of the play function is compossed. Each prepared tape deck is conducted to achieve the desired sound. Through the composition, an imitation of a not quite believable but still natural and slightly eerie soundscape with the audible characteristics and effects of tape recording and manipulation is introduced. The cassette shells are split in half so that the whole length of the tape loop is visible. The movement of the tape sets the cassette shells swinging like cuckoo clocks from the Black Forrest (Schwarzwald) and like the cuckoo clock also the tape might become a representation of time and nature.
