For this purpose, the titles of the first level subsections (.1-.9) of division 780 in DDC issues 18, 19 and 20 were analyzed. The methodology chosen for this study was a multi-faceted ontogeny analysis. As a result, it is possible to affirm that the editorial exchange carried out to broaden the cultural context in the DDC, were relevant for the conceptual revision and the breaking of biases previously verified in the music class. The analysis demonstrated how a classification scheme can not solve problems generated by a specific domain alone, necessitating the addition of other forms of organization (as discussed in division 780). The organization and treatment of documents in music is still under development in the area of Librarianship and Information Science, so this research can contribute to provide theoretical assumptions and other perspectives to future works.61-71porOntogenyDewey Decimal ClassificationBibliographic classificationMusicDDC 20th editionArtigoWOS:000489331700006
