Music has always been a great part of human life. While we listen to music or play an instrument, we activate all our senses and experience the music. Music has an impact on child since birth, so it is necessary to offer him quality musical stimulants to help in a future formal music education. As a child's development is going through certain stages, learning music also happens gradually. Aristotel was also intruiged by connection between music and emotions and he considered music as an integral part of ideal educational system because it has the ability to arouse and calm emotions and can influnce the formation of good character (Gabrielsson and Juslin, 1996, according to Dobrota, 2012). Children discover a different world by listening to music. It awakens imagination, fantasies and emotions in them, a cheerful song encourages them to be active, and gentle and quiet songs create a pleasant and warm atmosphere. As they sing, it is natural for most children to start moving, dancing or devising choreography because they associate the words of the song with body movements. Because of this child's need to move when he hears music, it is very important to use music in working with children of early and preschool age. Many educators are not aware of their influence on the children's musical development and progress. Research shows that educators mainly use singing as the most common musical activity in working with preschool children, so listening to classical music and playing instruments remains neglected (Miočić, 2009, according to Habuš Rončević, 2014). By choosing valuable and quality musical pieces, it is possible to influence on the development of child's good musical taste and hollistic development. The goal of this final paper is to show a role that music plays in a child's development, with an emphasis on the emotional development, and what is the role of educators in all of that.
