Music has been represented in all walks of life throughout the history of human civilization. Music teaching and music education has almost the same long history. We associate traditional or folk music with the social customs, people and culture of that people. The importance of music education and teaching and its impact on cognitive, emotional and social development has been shown in many previous studies. The aim of this research was to see the extent to which traditional music is represented in music culture textbooks. The research analyzed 24 music culture textbooks intended for primary education of primary school in the Republic of Croatia. The textbooks of three publishers, Alfa, Školska knjiga and Profil Klett, were analyzed, of which 12 textbooks were published in the period from 2006 to 2018, and the other 12 in the period from 2019 to 2022. The analyzed textbooks showed a satisfactory representation of traditional music in the period from 1st to 4th grade of primary school. Each analyzed textbook contains a certain number of Croatian traditional music and traditional music created outside the borders of our country. Also, almost every textbook contains a number of musical examples intended for singing, as well as musical examples intended for listening. In conclusion, the analyzed textbooks are adequately designed and the traditional music of Croatia can be compared on a cultural level with the traditional music of the world. By incorporating traditional music into textbooks, the rich folklore heritage of the Republic of Croatia is preserved from oblivion, and students and children encounter it from their earliest school age.
