The music has a great effect in mankind nowdays. The world as we know today would be hard to imagine without singing, dancing, concerts and all the things that the music has impacted. Music has even greater meaning when it is known that it has a positive effect on the human, and the child in the development. Nowadays, music in elementary schools is represented through one school hour, and that is most certainly not enough, taking into account all the positive effects that can be produced among the population. The music is available and ubiquitous in the 21st century, and it is not surprising that the cognitive, psychomotor and social development of personality are greatly affected. The most frequent choice of musical activity for most people is the singing choral. Therefore, this research is trying to compare and clarify differences in the organisation and work of Church choirs in the territory of the Republic of Croatia and Bosnia and Herzegovina. The results were collected by a survey questionnaire and two hypotheses were finally set. The first hypothesis was sought to prove that there were certain differences in the organization and work of Church choirs in larger and smaller parish communities and that there were no significant differences between the organisation and the work of Church choirs in the Republic of Croatia and Bosnia and Herzegovina.
