relativity +/-[n°1]

relativity +/-[n°1] rests on a minimal black metal frame: two black iron plates, 25 × 25 × 1 cm, with an electric heating plate pressed between them — the heat source withdrawn into the thickness of iron, unseen, only heard. The plates were cut in the studio; as the work was welded together, spatters of slag fused onto their surfaces. These residues of making were never cleaned away; instead, they became the work's true sounding body.

Through repeated cycles of heating and cooling, slag and iron expand and contract at different rates. One heat, two materials, two responses — and it is within this differential that sound is born: crisp, rhythmic, like a pulse driven by heat. If what the body perceives is only ever difference, then here difference no longer waits to be perceived — it makes itself heard. What we hear is neither the iron nor the slag, but the interval between them.

These minute sounds are gathered and amplified by a highly directional microphone suspended above, and reach the listener through headphones. The microphone is an ear extended beyond the body, pushing hearing into scales the skin cannot reach; the headphones fold listening into a one-to-one intimacy — alone with a plate of iron, you hear it recount the history of its own making. With every passage of heat, the scars of its welding sound again.

relativity +/-[n°1] 由一座極簡的黑色金屬架承載：兩片 25 × 25 × 1 公分的黑鐵板，中間夾著一片電加熱板——熱源隱身於鐵的厚度之間，不可見，只能被聽見。鐵板於工作室中切割而成；焊接組裝的過程裡，飛濺的焊渣附著於板面。這些製作留下的殘渣未被除去，反而成為作品真正的發聲體。

在反覆的加熱與冷卻之間，焊渣與鐵板以不同的速率膨脹、收縮。同一股熱，兩種材質，兩種回應——聲音正是在這道落差裡誕生：清脆、富有節奏，彷彿由熱所驅動的節拍。若說身體所能感知的，從來是差異——那麼在這件作品裡，差異不再只是被感知的對象；它自己發出了聲音。那不是鐵板的聲音，也不是焊渣的聲音，而是兩者之間的聲音。

這些細微聲響由上方的超指向麥克風採集、放大，觀眾透過耳機聆聽。麥克風是一具替身體延長的耳朵，將聽覺推進到皮膚無法抵達的尺度；耳機則把聆聽收攏成一對一的親密——你與一塊鐵板獨處，聽它訴說自身的製作史。每一次熱的行經，都讓那些焊接的疤痕再度出聲。
