This work describes an authoring environment for dance shows that can both be used as a mechanism to synthesize virtual performances and as a tool to assist the planning of choreographies, allowing design and visualization of full motion sequences. To this end, we explore adaptations of techniques for leveraging motion capture data to an application that makes extensive use of musical references. We also discuss methods for controlling the way dancers move on stage as a group, creating formations and following trajectories. Finally, we propose an integrated platform, which suggests a new form of collaboration between artists, allowing the show to naturally evolve from iterative contributions of dancers, musicians and choreographers. In this way, we indicate how graphics technologies can be used not only to facilitate creation but also to suggest new forms of artistic expressions.
