This book brings you along the co-production process that took place in the frame of Mapping - A Map on the Aesthetics of Performing Arts for Early Years. Starting from the division into four groups, each focusing on a different pillar of performing arts (image, movement, sound, and word), sixteen of the partners embarked on a journey of practical workshops, online discussions, rehearsals, try-outs, and touring performances, in strong connection among them and with the four researchers investigating their work. This journey, impacted in many ways by the events that have shaped the five years of the project, led to the creation of 27 new productions dedicated to children between 0 and 6 years old that carry in them the traces of the entire process and Mapping research. The 16 articles collected in this book give an insider’s view of the journey, allowing for a greater understanding of the many details behind each partner’s artistic path.
