Dahl, Luke and Robaszkiewicz, Sébastien (2012): For novices playing music together, adding structural constraints leads to better music and may improve user experience. In: Adjunct Proceedings of the 2012 ACM Symposium on User Interface Software and Technology 2012. pp. 85-86.

“We investigate the effects of adding structure to musical interactions for novices. A simple instrument allows control of three musical parameters: pitch, timbre, and note density. Two users can play at once, and their actions are visible on a public display. We asked pairs of users to perform duets under two interaction conditions: unstructured, where users are free to play what they like, and structured, where users are directed to different areas of the musical parameter space by time-varying constraints indicated on the display. A control group played two duets without structure, while an experimental group played one duet with structure and a second without. By crowd-sourcing the ranking of recorded duets we find that structure leads to musically better results. A post experiment survey showed that the experimental group had a better experience during the second unstructured duet than during the structured.”
