This conclusion presents an overview of the key concepts covered in the preceding chapters of the book. The book proposes the understanding of interactional processes found in group creativity, and the majority of it is devoted to the presentation and elaboration of a theory of symbolic interaction in groups. This theory builds on prior studies of group creativity in many disciplines, and analyzes the processes whereby group creativity results in emergence from improvisation. The book explores group creativity in music and verbal art. It discusses the creative group interactions of musicians and actors that are performed for the benefit of an audience. The team works without a script, and thus its activity is collaboratively improvised; and the outcome is uncertain and thus is emergent from the group dynamic. Communication scholars focusing on interactional synchrony were some of the first to identify the importance of group interaction in everyday social activities.
