摘要: 本論文目標為實作一個能夠依據情緒自動產生低限風格音樂的自動作曲系統,使用者透過簡單的點擊介面,可快速大量產生不重複的樂曲。樂曲以多段樂句組成,每段樂句源自於模仿低限風格作曲家Philip Glass的作品,透過音程、Pitch Class等樂理分析,使產生的音樂能呈現低限風格的特色。系統的情緒參數分別為激昂度與正向度,兩者交叉組成二維情緒平面。將各個樂句與每項音樂特徵透過公式或回饋問卷確認其情緒定位,系統根據設定的情緒選取適合的樂句與音樂特徵,最後產生具有特定情緒的音樂片段。完成的系統經回饋問卷得知,滿分10分,好聽度為7.7分,激昂度差異為7.9分,正向度差異為7.1分。本系統能作為未受音樂訓練者的簡單作曲之用,例如自製影片配樂。
This thesis is to design and implement an emotion-based minimalism style music composition system. The users of the system can generate music easily by clicking the GUI. The music is composed by several segments, and each one is made by imitating the minimalism composer Philip Glass’s works. Through the analysis of musical structure, it makes the product of system showing minimalism style. The parameters of the emotion module includes valence and arousal into x-axis and y-axis, so it is also called two-dimensional emotion plane. Then find the emotion position of every musical features and segment, therefore the system can select suitable parameters to generate music. In the questionnaire feedback of system, the music pleasant degree got 7.7 out of 10, the arousal differenciation got 7.9, and the valence differentiation got 7.1. This system can become an easy-to-use composition tool for the people without musical training.
