This study explores the cultural and moral narratives in the contemporary Vietnamese rap song “Nau an cho em” by Den Vau. The research employs a corpus-based linguistic analysis to dissect the song’s lyrics, uncovering themes and messages that resonate with broader societal issues in Vietnam. The analysis reveals four key themes: the resilience and hope of children in Vietnam’s mountainous regions, the empowerment through education and self-improvement, the juxtaposition of natural beauty with hard realities, and the portrayal of community and collective identity. These themes highlight the song’s portrayal of the challenges faced by marginalized communities, the transformative power of education, and the importance of communal support and unity. The study demonstrates how contemporary Vietnamese music, particularly Den Vau’s work, transcends entertainment to offer profound insights into social commentary and moral reflection. It underscores the role of music as a medium for cultural expression and societal discourse in contemporary Vietnam.
