Music education in schools has always been present in the Croatian educational system and was subject to various changes in program. With the introduction of the Croatian National Educational Standard (CNES) in 2006, the Croatian educational system, and Music Education alongside of it, has been directed to an open model of education. Even though primary school education moved to the open educational model with the introduction od CNES, this path for Music Education only began in 2010 with the introduction of the National Education Curriculum (NEC). The didactic and methodic openness has been confirmed with the latest version of the document in 2019 wich states that learning music has a mainfold social role: integral development, development of musical preference, love for music, the student's general image of the world, stimulates interest and the need for music while constructing the student's identity. This new curriculum philosophy defined by the latest documents, promotes inter-subject relations within class conduction. Alongside mandatory and recommended content, the curriculum contains examples of connecting music education content with other artistic or non-artistic subjects, thus acquainting the students with different cultures, thoughts and customs. In other words, the student's intercultural sensibility and perception of the world are being developed. The inter-subject relation of music with other subject areas offer a wide array of useful skills and knowledge. The open model and the stimulation od inter-subject relations offer great potential while teaching and learning and it aims towards competence development in students, apropos skills, knowledge and competences.
