With the vocal apparatus, man produces sound through the process of phonation. A child’s voice has its limited range that expands during the early and preschool period. We distinguish two registers of children's voice, frontal and thoracic. Children's singing has its indispensable components: singing posture, breathing, diction and articulation, dynamics and artistic expressiveness. Children's vocal abilities are limited, and the vocal apparatus of gentle build. Therefore, care should be taken when singing not to damage the voice. Dangerous speech behaviors such as shouting and overvoting are not desirable, while vocal hygiene should be nurtured. By knowing the vocal abilities of children and predispositions, we can systematically act with various vocal exercises adapted to the child's way of learning. In preschool institutions, it is desirable to work on the development of vocal abilities in group and individual mode. The educator as a methodologist of music culture must be well prepared, educated. The educator first perfects his vocal abilities. It helps children with proper breathing, posture, intonation, articulation, diction and artistic expression and identifies the individual needs of each child. In the kindergarten Marjan in Split (Grdelin facility), various vocal exercises were conducted focused on the development of the components of children's singing vocals in the form of symbolic games. Despite no experience with vocal exercises before, progress could be seen as the children showed great effort and interest in learning.
