東方樂器無論在音色和時間性都與西方樂器有差異。就單純地撥彈一條古箏上的弦：手指用怎樣的速度、力道、角度去接觸弦，又施予了怎樣型態的壓力，弦共振後餘韻的時間感...等，有許多的細節能取決一個音的性格。此作試圖運用即時錄放的電子音樂，將接觸式麥克風置於不僅能接收演奏者觸碰弦的聲音細節，還有共鳴餘韻的位置，去放大細節的聲響。
此外，演奏者的手指上裝了一個感應器，來偵測手指移動的角度與影像互動，所以投影光源的部分完全是由演奏者的手指行為來即時操縱。
Eastern instruments differ from Western ones in both tone and temporality. Take the simple act of plucking a string on a guzheng: the speed, strength, and angle at which the finger touches the string, along with the type of pressure applied, all influence the resonance and the lingering sense of time in the sound’s afterglow. These fine details shape the character of a single note. This piece attempts to use live-looping electronic music by placing a contact microphone not only to capture the subtle sounds of the performer’s touch on the string but also the resonance and decay, amplifying these details. Additionally, a sensor is attached to the performer’s finger to detect the angle of movement, interacting with the visuals. The projected light is entirely controlled in real-time by the performer’s finger movements.
