Abstract: A music representation model based on relative pitch and relative time length was proposed. This model well represented the same melody under different performance conditions. Based on the model, a music style classification algorithm was proposed to measure music style through melody Mutual Information. The algorithm’s time scale was close to that of syncopation algorithm under Unigram and Bigram models. The algorithm well supported music style classification among multi-styles.

Key words: melody, mutual information, syncopation
