Abstract: This project attempts to artificially recompose music which would retain the styles of the original compositions based on the application of complex networks. Specifically, the combined use of the concepts of motifs and complex networks has been found fruitful in the composition of music. Composers create fragments of music, which are called motifs, through sudden inspirations from a person, a scene, a thing, etc., and then develop music around these motifs. A motif is the smallest unit in music and can be considered as "germ" of music composition. Based on this theory, two kinds of motifs are defined, namely, rhythmic motifs and tonal motifs. These motifs are constructed, respectively, from rhythmic networks and tonal networks. Then, these two types of motifs are combined to generate composite motifs. Lastly, music can be recomposed by using the composite motifs. Music from Teresa Teng and Jay Chou, two famous Chinese pop singers, are selected for experimental study. Several sets of music samples are generated based on the works of these two singers. In addition, music motifs can be linked with network backbones. They all correspond to the repeated segments of a given piece of music.
