After a first volume dedicated to dance practice, this book completes the "Youth" series developed by the CN D for children and young teenagers. To see a dance performance is to perceive, to be carried away, to feel, to imagine. To be a spectator is to be active and to live a personal experience. In this book, written by Laurence Pagès, a choreographic artist, and Sylviane Pagès, a dance historian, children will find a variety of ways to refine and train their eye for dance, whether it's happening right in front of them, on their screens or in theatres.
