One second, two seconds... just as the clock hands move, time seems to flow sequentially. In music composition, the process of arranging sounds within the space of time is the act of structuring music through the sequential arrangement of notes. We remind ourselves that there is an illusion in this structure. Time, we believe, exists simultaneously, and what we perceive and distinguish is merely the boundary of that perception. Thus, we create a score for music, score I for a cycle. (국문)
