By applying the CNES (Croatian National Educational Standard), since the school year of 2006/07, teaching music is performed according to the open model. The teaching area of listening and introduction to music is according to the open model the only mandatory field. Other teaching areas are variable, ie. the teacher abides by psychological and cultural-aesthetic principles in the selection of the same. Music lessons aim to develop critical and aesthetic evaluation of music and the development of musical taste, and just actively listening to music achieves the goal of the subject. In this paper a survey was conducted that took place in several primary schools in Osijek-Baranja County during the period of three weeks of the school year 2014/15. The study included 38 examinees (class teachers). The opinions of class teachers were surveyed with the questionnaire. Also, for the purpose of research at the elementary school "Dr. Franjo Tudjman" in Beli Manastir, music lessons in the first four grades were observed. The purpose of the study was to monitor the implementation of active listening to music. Studies have shown that most teachers do not carry out the open model, only a minority implement it. Listening to music is not the central activity in music lessons. While listening, most of the teachers carry out active listening to music. It is also confirmed that teachers have a postive opinion about listening to music in music lessons and consider it essential for the development of the musical taste of students.
