(I) Studies have shown that even at birth a child responds positively and specifically to the tones of human voice. (II) Music in particular has been found to have a soothing effect upon a child. (III) In one such study a film of a new born baby was taken. (IV) When it was examined in slow motion it was found that tiny gestures on the part of the child synchronised with specific tones and syllables from parents. (V) Sounds other than the human voice, however, produced no such responses.
