Toru Takemitsu(1930-1996) is an important contemporary composer in Asia. His techniques of writing were influenced by Debussy(1862-1918), Messiaen(1908-1992), Webern(1883-1945) and Cage(1912-1992). He combined traditional Japanese aesthetics to create a unique musical style of his own. This paper is to research his work "I heard the water dreaming", aiming to resolve intrinsic relationships of structures between meaning ful musical units, as well as through the composer's life, to review his creative processes and traditional cultural backgrounds, in order to explore aesthetic experience (inductive) or integrity (the wholeness) of the subject. My approach is aiming to be equivalent of "conception" in Chinese poetic theory.
