The common characteristic of speech and music is sound, because in both cases sound is used as a mean of communication. The connection between music and speech is based on various forms of instrumental and vocal reproduction, creation and listening to music. For example, when a child sings a certain song, it encourages the creation of sound with the help of the voice taking into scope the correct pronunciation of sounds, while at the same time listening to music influences the ability of verbal expression. The development of speech is largely related to the environment in which the child resides. Subsequently, it is necessary to provide the child with an adequate environment for the development of speech in which the child must feel accepted, loved, and understood, with the aim of enabling development of speech and in the other areas as well. Positive surroundings are very important for children because they usually explore the space around them using the sounds in the environment. A child's sound improvisations are largely related to its spontaneous creative expression, freedom, imagination, and creativity. Using the acquired knowledge, children greatly enrich their vocabulary and apply basic concepts in the field of music. The game is also very important during this process because the game encourages children to actively listen to music, dance and perform various movements that are in accordance with the tempo and rhythm. The aim of the work is to investigate the development of speech and creativity with the use of music and singing in children of early and preschool age.
