To support cellists in analyzing their interpretation of a musical piece and comparing it to others, this work presents and explores possibilities to visualize musical data and motion-captured bow movements in virtual reality. The presented prototype utilizes consumer VR technology and, optionally, the OptiTrack motion capture system to record a cellist’s playing, providing different visualizations that can be viewed in real time as well as played back from recorded data. In this thesis, we propose a one-by-one mapping of the 3D path of the bow, supported by various synchronized 2D line charts that are placed in virtual reality. We map motion features, audio features, and computed metrics to the color and width of the respective segments of the 2D and 3D lines. To evaluate the proposed design a user study with two domain experts was conducted, showing potential use of the design and providing us with ideas for future improvements, such as an extension to augmented reality.
