At the beginning of the twentieth century, in France, few women dared to venture professionally into the field of music composition. The pioneers overcame important social and institutional obstacles, at the cost of struggles and strategies that we can hardly imagine today. The journal Musica, published monthly between 1902 and 1914, especially for women, offers a very rich showcase of this reality, not only through its texts, but also through the many photographs it contains. In this article, particular attention is devoted to Lili Boulanger who is the first woman to win the Premier Grand Prix of Rome in 1913.
