Antía Cores and Jesús Rodríguez, members of the Stellae group, have just recently published the article entitled "Analysis of cultural heritage in music didactic materials in Galicia" in the International Journal of Music Education.
In this publication, musical albums published in the Galician language are analyzed from the perspective of Galician cultural heritage (material and immaterial) with the aim of evaluating whether these resources that have been on the rise in recent years are adapted to the linguistic, musical, and cultural context of Galicia.
