The social spaces of northern Mexico and the United States are the protagonists of most of the proposals and stage cross-border and transnational cultural flows, armed violence, creativity and innovation, and adaptation to the impacts of the global economy. All these phenomena are crossed by digital contexts of production, circulation and consumption of symbolic forms and, as new forms of social life, of subjectivities and intersubjectivities that social scientists are just beginning to study.

This paper explores the role of music and emotions in the construction of transnational ties, based on two ethnographic vignettes related to nostalgia. On the one hand, this emotion prevails in the daily life of Mexican migrants in Houston, through their diverse practices, behind which Mexican popular music is present along with images of the terroir. On the other hand, in the context of the visit of migrants and their families to the places of origin in northeastern Mexico, popular music is heard to express their nostalgia and induce a nostalgic attitude in the spaces of family and social reunion, creating a distinct soundscape of the season of migrants' absence.
