It is an electroacoustic piece for tape and Erhu (Chinese instrument). Every sound from the tape is the reflection of transformation developed only by Erhu sound. Before start to write, I bring a Erhu player to a studio and did something randomly and saved those materials into my sound library where I found quite a lot of interesting things happened, which inspired me of writing a piece in a way of using the same materials and mixing together original sound and transformation sound.
