Considering the inclusion of 21st century skills in the education programs, which are emphasized in the 2023 vision of the Ministry of National Education, it is important to reveal the extent to which 21st century skills are included in the Music Lesson Curriculum. With this research, it is aimed to examine the compatibility of the achievements in the Music Lesson Curriculum (primary school-secondary school), which was renewed in 2018, with the skills of the 21st century. The research was created in line with qualitative research methods. The data used in the study were obtained by document analysis. In the research, all of the achievements in the Music Lesson Curriculum were subjected to content analysis. While conducting the content analysis, the compatibility of the acquisitions with the main skills in the framework of P21 and the sub-skills within these main skills were taken into account. In this context, a total of 179 acquisitions at the level of all classes were examined and divided into sub-themes on the axis of learning areas in the Music Lesson Curriculum. As a result of the research, it has been determined that the achievements in the music lesson curriculum don’t adequately reflect the 21st century skills and that no balance is observed in the distribution of the skills to the achievements.
