This small book describes specific techniques for working with young patients, using two powerful tools - music and play. Music and play turn to the natural states of children, and therefore easily remove their resistance and fears of an unfamiliar environment and help children develop imagination, memory and speech, get rid of fears, overcome shyness and aggression, learn to perceive color, sound, rhythm, coordinate the movements of their own body - and as a result, it is better to feel in the world of people. It can be a very useful tool for psychotherapists-practitioners working with children, as well as for educators and parents.
