Music lessons in Croatia are characterised by the existence of three areas that intertwine and complement each other. Thus, in music lessons, students will listen to music, participate in various activities regarding their musical expression, and learn about music. A music teacher can choose which activities of musical expression he will carry out in his own educational process, and he chooses them according to his own interests as well as the abilities of the students. This paper aims to determine the perception of upper primary school students regarding the musical creativity activities in music lessons. Students (N = 128) from two schools in the Vukovar-Srijem county participated in the survey, and one group of those students actively participated in musical creativity activities. The research results show that students generally have a positive opinion about musical creativity activities. The students who have participated in the musical creativity activities highly rate their competencies for participating in various creative activities.
