Prog. notes: This piece is intended to portray the soundscape and landscape of the rain in a dream by combining the sound of acoustic instruments (yangqin and percussion) and the computer processed sound. They are interwoven into a vast and illusionary soundscape and is shaped with the gradual process of change in pitch, rhythm, note density, texture, and etc. The instrumental part focuses on the dialogue between yangqin and the percussion instruments of definite pitch. For the electronic part, sound samples from cello and metals are transformed through granular synthesis and spectral editing to provide the background drown sound in contrast to the short sonority from live yangqin and percussion instruments and to thicken the overall timbre and texture. In addition, the bell-like or chime-like synthesized sound are used with reverberation and delay effects to produce different short sonority and spatialization as opposed to that generated by yangqin and percussion instruments.

《夢中的雨》這首作品旨在呈現夢境中雨之音景與雨中山水之景象,藉由點狀音色之樂器(揚琴、打擊樂器)搭配電子音樂的特殊聲響,交織成一片廣闊而虛幻的音場空間與聲音的幻境,並以音高、節奏音型、音符密度、織度等的漸變過程,作為建構此作品音樂流動性的手段。器樂的部分,集中在揚琴、固定音高的打擊樂器之間的對話;電子音樂的部分,則主要以預錄的大提琴聲、敲擊金屬的聲音等,經過粒子化合成、頻譜編輯等手法加以變形與拉長,作為現場點狀樂器演奏之外,背景的襯底長音,藉此增加整體音響的厚度;此外也加上鈴鐺似的合成音色,搭配殘響與延遲效果,建構一種相似卻有別於現場樂器的點狀音響與多層次的音場空間。
