| Summary: | 碩士 === 國立交通大學 === 工學院聲音與音樂創意科技碩士學位學程 === 104 === This thesis is for studying Automated Composition System Method (ACSM), including all music motivation and emotion structure parameters, based on the theory of Western Music. The theory of music alongside with motivation structure is what will be focused on here, unlike under its normal circumstances. Two different conceptual practical operation systems will be tested for ACSM. The first is to use notes parameters on the basis for probability distributions, investigating emotional arguments with the corresponding music parameters. That will produce a single melodic phrase. The second is based on the basis of both of the theory in music and its motivation structure, combining emotion parameters with the theory of Pitch Class Set in its depth of tonality, tuning, and harmonic progression with generating method of motivation structure to complete the production of phrases. Two ACSM were practically tested and discussed separately in this paper, the two systems were triggered by four emotional arguments to compare all produced phrases respectively. The discussions to differences of mood, tonality, the relationship to motivation structure, and the interaction between the three are further analyzed. Perfection and the refinement of ACSM are to be achieved after this study.
