The Harmony Group is an open, performative study group exploring the idea of harmony and its relation to control. In the spring of 2015, we met four times for expeditions, discussions, and performances, studying topics such as chaos, homeostasis, negative feedback, and hierarchies. In the fall, we will focus on the concept of the self organised system under five engagements. The group itself will be a self organised system. Every meeting is open to new participants.
