《痕》配器為長笛、鋼琴、小提琴、中提琴、大提琴以及擴聲的素描紙。整曲的發想由筆觸與紙張摩擦、鑿刻的聲響，延伸至樂器調和一連串的聲音織度變化。
擴聲的紙張表面黏貼了接觸式麥克風，為了獲得更佳的聲音共鳴，四角黏貼了紙條微架高，如鼓膜的原理般，讓紙筆摩擦之聲響震動更清楚。
整曲由擴聲紙的演奏素材延伸，面向可分為橫向與縱向。如紙張書寫、弦樂拉弓、鋼琴弦內滑奏皆為橫向。反之，筆尖敲打紙張、弦樂擊弦、鋼琴彈奏皆是縱向。

This piece explores the natural connection between the movement and sound of the instrument playing, from the sound of writing on paper, expand to other instruments. The physical movement is categorized into two directions roughly: horizontal and vertical. Paper writing, strings bowing, piano rubbing are horizontal actions. On the other hand, percussive actions, such as hitting strings, playing piano on keys are related to vertical movements.

The rectangular amplified paper attached with contact microphone underneath for getting better resonance, as the drum membrane to amplify writing voice details.
