The article analyzes textbooks and offers an insight into the didactical manuals written in early socialism. Textbooks of modest volume, published at the end of the forties and in the fifties of the last century, reflected the basic requirements of educational policy. The main goal of music education was to educate students to sing by notes. The publications were conceived as theoretical instructions for musical literacy. The first didactical manual written by Joža Požgaj was published, which in its revised version (...) was used in music teaching for many years. Textbooks written in the first half of the 1960s, after the educational reform, were adapted to children’s age, while didactical manuals focused on enriching the lessons with songs, literary examples, games, stories, the use of school instruments etc. The attention shifted from music literacy to singing as dominant activity in music teaching, but again with the aim of acquiring basic musical vocabulary.
