The improv code: 20 hacks from professionals ...and YesTicket is part of it!
"The Impro Code" brings together 20 renowned improv professionals from German-speaking countries, who each share a specific hack from their practice. From applied improv in business and storytelling techniques to moderation methods and resilience techniques - each chapter offers immediately applicable ideas.
There is also a special highlight for our community: Fabian from YesTicket brings his years of experience from setting up YesTicket and supporting hundreds of cultural groups directly into the book. He takes a look behind the scenes of the "empty chair syndrome" and shows how to turn the "principle of hope" into a reliable system for full auditoriums by using clever processes and the right attitude.
