|Abstract||Jingju (Beijing opera) is a Chinese traditional performing art form in which theatrical and musical elements are intimately combined. As an oral tradition, its musical dimension is the result of the application of a series of predefined conventions and it offers unique concepts for musicological research. Computational analyses of jingju music are still scarce, and only a few studies have dealt with it from an MIR perspective. In this paper we present the creation of a corpus of jingju music in the framework of the CompMusic project that is formed by audio, editorial metadata, lyrics and scores. We discuss the criteria followed for the acquisition of the data, describe the content of the corpus, and evaluate its suitability for computational and musicological research. We also identify several research problems that can take advantage of this corpus in the context of computational musicology, especially for melodic analysis, and suggest approaches for future work.
