La movilidad de las músicas populares en América Latina en los años 30 del siglo XX. Las voces al unísono

Articulating, on one hand, some recent studies on popular music from different Latin-American countries and, on the other hand, some searches in publications like song books, and gossip magazines, a research is conducted about the mobility of popular musics through different countries in the region. It identifies the increase, presence and dialogue of the travelling musics with those deemed as national musics during the 1930s. In this decade, the cultural industry of the radio, records and cinema consolidated under an intermedial process as the entertainment and broadcasting spaces that, excluding the cinema, transcend the public spaces to settle into the private spheres.
