| Summary: | 碩士 === 國立政治大學 === 資訊科學學系 === 95 === Many studies have indicated that music plays a guiding role of human emotions. In the theory of music therapy, the psychological impact from music is mainly in guiding emotional changes. But, most of the past studies and experiments, which were about the characteristics and features of music, focus on identifying the emotion of music contents. In this paper, our goal is to find music that leads a person’s emotion to positive side by analyzing music features; we also hope to find out the characteristics and the relationships among music.
Before analyzing the music, we define the music features, and use these features to express the contents and the characteristics of music. Using these features to express music, we assume that the songs that guide emotion to similar changes should be similar to each other. After analyzing the music, we found out that if the music features are sequential, the searching result will be more accurate when we want to find some songs that guide human emotions to similar changes. This finding can be used in music therapy to provide the music therapists an alternative way of choosing music.
