Research Unit for Music and Media Technology Abstract: [ PDF ] Analyzing the motif structure of rhythmic sequences is a central issue to music psychology, music theory, and computer applications in music. There are many approaches to the topic by music theorists, psychologists, and computer scientists, yet a model capable of integrating the different findings is still missing. The Integrated Segmentation and Similarity Model (ISSM) presented here is a newly developed model designed for this integration. It is based on a structural representation with detailed information on individual parts, a fuzzy system for rating structural alternatives, and algorithms for computationally efficient structure-recognition and system-optimization by machine learning. The design of the ISSM is described with a focus on musical motivation, and some results of the implementation and evaluation are discussed. |
