In terms of sound art, Paul Panhuysen is well-known for his long string installations, yet he has produced a vast amount of other sound installations using different materials and sound sources ranging from various instruments to animals such as birds. “Pendulum Change Ringing” was displayed at Pand Koloniale Waren in Hasselt (Belgium) in 2012. Twelve engraved Turkish metal platters, each mounted onto a black plastic bin, were placed in a 20 meters long row. The rim of each platter is hit by a metal pendulum operated by a tiny electromotor. Each hit causes the platter to resonate with a rich sound texture full of dissonant overtones. During the recording, the twelve pendulums are activated one after the other. The paces at which they swing differ due to their rods having different lengths. This causes interlocking rhythmic patterns to emerge that become more complex with each step and never stay the same. Hits aggregate into clusters, then thin out again. The sound is not chaotic, though. “You might call Pendulum Change Ringing a typical Paul Panhuysen piece: it works according to a system, quite a simple one in fact, but its effect surpasses that apparent simplicity by far.” (René van Peer)
