Klingen; klang II, uses mild steel and green oak with loudspeakers and contact microphones, amplified and processed with reverbs. The title is continued from previous works as it is a series that can be re-imagined in each iteration, but the fundamentals will be somewhat similar. The material relationships within the sculpture emerge visually and sonically. The resonances of the metal are excited and amplified with the contact microphones, modulated by the contingent movement of the material as it is vibrated by the force of the sound. I have used reverbs and decay timing to further excite areas of the metal so that, once established, the resonant frequency you hear is under interference from other emerging frequencies causing the sound to change as a new resonance is established.
The way in which you performatively engage with the sculpture, moving around it in the space, is important to the work as a listening experience. You may start to notice areas where the frequencies cancel each other out or new ones seem to reveal themselves as the sound starts to reveal the acoustics of the room itself. The sonic performance of the sculpture is something which emerges from the material relationships enacted within it. I include the technical equipment in the materials which make up the sculpture as their agencies have equally distinct roles in that relationship.
I chose green Oak as the material to make a structural frame from as the material is irregular and in a state of flux. The water content of the wood changes over time causing it to move, twist and crack eventually coming to a somewhat stable state. The poetic nature of this process resonates with the way in which I am generating sound. Although it may not be as apparent as the metal vibrating before your eyes, the frame itself is also proceeding with its own dynamic changes but on a much longer and perhaps imperceptible time.
The colouration of the frame is a material relationship that was revealed in processing the material and training at a specialist in oak framing. The Iron in the steel reacts with the tannins in the oak to produce the hue you see; I dissolved the steel fillings created from cutting the metal to create a ferrous wash. This is a chemical reaction which exists within the two materials and the effect is distinct to the relationship of these pieces of oak and the steel I am using to create sound.
