What can infants hear? Is it useful for them to sing and listen to music? How can their musical development be improved? In this book, Tafuri explores these and other questions through a longitudinal research project devoted to studying musical development from 0 to 6 years in children, with particular attention on the ability to sing in tune. During these 6 years, the subjects would have a regular music education experience with their mothers and often other members of the immediate family. This book reconstructs the development of human musical abilities and puts forward an educational perspective based on the results of the research. The book will be of crucial interest to parents and music educators so that they can have scientific, theoretical and methodological foundations for their educational strategies.
