The purpose of this paper is to clarify the features of the Sixth National School Music Week, which was held in the Weimar Republic in Germany in 1927. The paper considers the following five perspectives: (1) the impact of reform pedagogy; (2) contents of school music classes and their expansion; (3) curriculum; (4) the relationship of music to other subjects; and (5) music education outside school. It has been revealed that the Sixth National School Music Week obviously employed the concepts of reform pedagogy such as Erleben and Arbeit; and that there was also an attempted expansion of the contents of school music classes. These features were similar to those observed in the First and Fifth National School Music Weeks. There were, however, differences from the First and Fifth National School Music Weeks in terms of interpretation of the curriculum and an emphasis on the relationship between music and other subjects. One significant feature found was that alongside the aforementioned discussions on music education at school, the Sixth National School Music Week directed its interest to music education outside school, as was consistently the case with the First and Fifth National School Music Weeks.
