       Program notes:

        The title Yun, in Chinese, is used to describe several ideas: sounds in music, rhymes in poetry, and the meaning of elegance.  My idea was to transfer these meanings into different musical gestures and textures, and to develop them in various ways.  The main musical ideas are the wild and improvisational-like melodic lines (presenting by solo instruments) and the recurring accented two-note figures (usually very rhythmic), which contrasts with the graceful and lyrical middle section.  Structurally this composition is through-composed rather than following a certain form; however, new materials are developed from the old ones.  Although I incorporated theoretical thoughts in developing motivic ideas, I tried to let the music itself lead throughout.
