Phase Transition (相變) : for Prepared 21-Stringed Zheng Solo (2008)

Performed by Yi-Chieh Lai, Transformation: Contemporary Taiwanese Zheng Music, 2008

Program Note:

In physics, “phase transition” refers to the transformation of matter from one phase to another. In this work, the composer tries to represent the three states of matter (solid, liquid and gas) and their transformations (melting, vaporization, condensation, freezing, and sublimation) by means of timbral and textural manipulations.

The composer chooses 21-stringed Zheng, a Chinese traditional unfretted zither, as the solo instrument, which has been prepared. The player also has to play with different tools——bow, superball, paper, and clips, for example——to make variant sound effects in the performance. Through these performing devices, the composer hopes to create timbral diversity and to seek the new possible sonorities out of the traditional instrument.


在物理學中,「相變」意指物質從一種狀態轉變為另一種狀態的過程。本曲企圖以不同的音色、織體來表現物質三態──固態、液態、氣態──以及熔化、汽化、液化、凝固、昇華等轉化過程,製造音樂的「相變」。本曲將二十一絃箏加以預置,並在演奏中使用多種輔助工具(如弓、彈力球、紙張、迴紋針),試圖透過預置、不同的演奏媒介與演奏方式,創造出更多元的音色變化,從傳統樂器中尋找新的聲響效果。
