The topic of this thesis is focused on influence of music on child's cognitive, motoric, social and emotional development. The aim of many studies is to determine the general influence of music on child's development. Many studies have shown that music education and listening to music have positive influence on child's development. It is important to apply music as an intermediary in every part of the teaching process in order to have the role not only in aesthetic education but also in the general development. For the purpose of this thesis research took place in the year 2017. /2018. in three primary schools (Višnjevac, Petrijevci, Sotin). The aim of the research is to find out teacher's experiences of using music in nonmusical subjects and attitudes towards the influence of music on child's development. The group of 32 teachers participated in the research. They had to fill in the questionnaire anonymously. The research was conducted in May 2018. The results of the research have shown that teachers have a positive attitude towards using music in non-musical subjects, mostly used in arts classes. It is mainly used as a motivation in the introductory or final part of the class and teachers think that music has a positive impact on the general development of the child.
