日常生活中所發生的細微變化，經常不易察覺，也許可以，但我們的感官很難用絕對的數值或量化去做描述。在東京駐村期間，注意到冬季因熱脹冷縮而產生細微聲響的鋁製窗框，這些膨脹與收縮的活動，就發生在細微的溫度變化時，我們的皮膚可以感知溫度的差異，但無法絕對的分辨精準細微的變化，因此對身體而言，這些細微的變化都是相對下的感覺與差異。

 

透過特製的加熱裝置，內部的特殊結構在溫度的變化下，彼此間些微的伸縮，如呼吸般的韻律，在看似平靜的裝置外觀，卻暗藏著細膩活躍的聲響，靜靜發聲。「相對性 +/- 」RAW有兩個金屬加熱裝置，其中一個金屬裝置將會切割開，透過剖面，呈現原始內部結構和狀態，包含加熱到發紅的電熱裝置，另一個則維持原貌，讓觀者直接看見其內部的加熱與冷卻過程所產生的視覺與聽覺變化，裝置加熱與冷卻的循環時間為17分鐘，當一個裝置在加熱時，另一個就在冷卻，現場兩支麥克風分別收兩個金屬裝置加熱冷卻過程的聲響，透過耳機，一左一右聲道，呈現兩邊相對的聽覺。兩個螢幕的內容分別是這兩個裝置在錄音室裡紀錄的低躁版聲音和影像。

 

The slight changes in our daily lives are hard to detect; perhaps it is doable, but it is difficult for our senses to describe precisely these changes using numerical and quantitative data. During the residency period in Tokyo, Chang Yung-Ta noticed that aluminum windows created a minute sounds due to its shrinking and expanding in winter. When these shrinking and expanding happen because of the subtle temperature change, our skin is a great detector of the difference but it is unable to differentiate precise and subtle changes—it can only be compared to one another.

 

With a special heating device, the internal special structure undergoes a slight change of temperature, causes a contraction and breathing like rhythm. Under the relatively calm exterior, a faint delicate sound pulsates. “Relatively +/-“ Raw has two metal heating devices, with one of these heating devices cut open to show the internal structure and state, including the glowing red hot electric system. The other heating device keeps its original form, letting the audience directly see the heating and cooling as well as the changes is sound due to this change of temperature. The heating device heats and cools with a loop of 17 minutes. When one of these heating devices heats up, the other cools down.  Two microphones, each recording the sound of a heating device separately, stream the two sets of sound into a pair of earphones so that the left ear and right ear are playing contrary sounds. Two monitors display sounds and images of each heating devices that recording in a studio room separately.
