Music is a powerful tool that affects people in different ways. It can be defined as a combination of knowledge and skills, i.e., the art of organizing sounds with respect to time; the art of combining sounds according to a set of rules (that vary depending on the place and time); or as the product of this art. People encounter music since birth, and they start their music development during the prenatal period. Music has played a significant role in upbringing and education for a long time. Children’s early and preschool years are the most important for their general development. Therefore, music education in preschool institutions is of key importance in the process of education and upbringing. Upbringing is defined by Vukasović as the process where people are formed as human beings with all of their traits and characteristics. It encompasses all the elements of a child’s development, including music development. Music education emphasizes the cultural and aesthetic dimensions and it facilitates the creative process in children. Music has a positive effect on all aspects of children’s development and it helps them acquire and develop their motor, cognitive, creative, and affective skills. Music education and development of children in their early and preschools years can be realized through various methods, i.e., music activities, for instance: singing, playing an instrument, listening to music, musical expression or creation, movements, practical tasks, games and other kinds of fun social activities. In such a process of developing a child’s musical potential, there are three mutually-related preconditions: a child’s musicality, music skills and music intelligence. The success and effects of music education largely depend on the childcare worker’s motivation, willingness to learn, expertise, and competence. What is more, it is extremely important to set up a curriculum related to children’s early and preschool education which recognizes music development as an important aspect of a child's development as a whole.
