Music and musical activities are part of the general development of a child from the first to the fourth grade of primary school. The first chapter of this paper deals with the influence of music on the general development of a child. Music and musical activities, ie education, can affect children's cognitive, social, emotional and psychomotor development. Children themselves decide to learn music because there are children who are more or less interested in music learning. The continuation of this chapter refers to music and methodology in religious education, as well as motivational techniques. Music is present everywhere, including in religious education. If a religious teacher has any affinity for music, he can put music into the lessons in interesting way. Music in religious education is most often used as a prayer at the beginning or end of a class or as a motivation. In addition to music, other motivational techniques such as language and art motivation and meditation are present in religious education. Also, musical motivation is described in detail and what is the role of music in religious education. The second chapter refers to liturgical music and the Croatian liturgical songbooks Pjevajte Gospodu pjesmu novu and Slavimo Boga. In this chapter we state what the liturgy is, liturgical music, and what influence liturgical music have on people. The sung parts of the Mass and the content of both songbooks are also described. Along with the content of the songbooks, theological - ecclesiological, anthropological, Marian and occasional songs from the mentioned songbooks are listed. In the third chapter we state the functional role of liturgical music in religious education.
