Summary: Since a few years, classification in music research is a very broad and quickly growing field. Most important for adequate classification is the knowledge of adequate observables or deduced features on the basis of which meaningful groups or classes can be distinguished. Unsupervised classification additionally needs an adequate similarity or distance measure and grouping is to be based upon. Evaluation of supervised learning is typically based on the error rates of the classification rules. We first discuss typical problems and possible influential features derived from signal analysis, mental mechanisms or concepts, and compositional structures. Then, we present typical solutions of such tasks related to music research, namely for organization of music collections, transcription of music signals, cognitive psychology of music, and compositional structure analysis.
