The baby not only likes to be sung to, but is very interested in and enjoys her own vocalizing. The lullaby is a direct and powerful emotional catalyst for communication and bonding between parent and child. Its simple beauty and emotional context has even inspired great composers like Schubert and Brahms. Nursery rhymes, finger and toe plays and tickling games are the young child's musical repertoire. True children's games that evoke an emotional response are perfect examples of art in a child's world.
Art involves tension and climax.
A movement of a sonata by Beethoven has similar emotional development to a simple child's game. Through the game, the physical human contact between adult and child creates a close feeling. The touch, physical closeness and facial expressions exchanged between the adult and child are similar to the interaction when singing a lullaby. When the climax of the tickle is experienced, an emotional high occurs. Repetition of this short game initially helps the child to become involved and also helps to create a mood.
