Virtual musicians have become a remarkable phenomenon in contemporary multimedia arts. However, most of the virtual musicians nowadays have not been endowed with the ability to create their own behaviors or to perform music with human musicians. In this paper, we firstly create a virtual violinist, who can collaborate with a human pianist to perform chamber music automaticallywithout any intervention. The system incorporates techniques from various fields, including real-time music tracking, pose estimation, body movement generation, and style transfer from music to visual arts. In our system, the virtualmusician’s behavior is generated based on the given music audio alone, and such a system results in a low-cost, efficient and scalable way to produce human and virtual musicians’ co-performance. The proposed system has been validated in public concerts. Objective quality assessment approaches and possible ways to systematically improve the system are also discussed.
