There is an old phenomenon in theatre arts: Education! And there is a new tendency: theatre arts for the very young! The relationship to education is clear, but what about the profit for the arts? The world of children as a horizon of experiences? The role of music as a dramaturgical element? Is it needed to divide the performance in actors and spectators? Is there a special age for a successful reception? How much should theatre artists be confronted with the physical and psychological development of children? It seems that Theatre for Early Years is a work in progress. There are more and more examples on the stages of the world: In Europe, in the States, in Australia. A variety of different perspectives are included in this research in performing arts from birth to three. The authors are reflecting their work, their observations, their directorship - to discover a new audience, to accompany the new generation in aesthetics, to make the signs of the time transparent. And maybe the development of Theatre for Early Years is a new challenge to renew the language of theatre, to establish an art of simplicity for the complexity of theatre.
