This paper aims to delve into the complexity of identity within cross-cultural music, focusing on the interaction and integration of traditional music from immigrant communities with the popular culture of the host country. In the context of immigration, traditional music serves not only as a vessel for the continuity of history and culture but also plays a crucial role in the formation of community identity. As popular culture rises, the expression of traditional music is influenced by various factors, gradually incorporating new elements. This integration reflects both a process of cultural adaptation and a profound examination of identity. Through the analysis of specific cases, this paper reveals the positive role of music in fostering cultural exchange and enhancing community cohesion, while also addressing potential identity crises and cultural conflicts that may arise. This dual influence underscores the significance of music as a tool for self-expression and cultural preservation. Ultimately, the paper summarizes the multiplicity and fluidity of music within immigrant communities, emphasizing that in the context of globalization, music functions not only as a reflection of identity but also as a means for individuals and groups to reshape themselves amidst cultural convergence. Through an interwoven analysis of tradition and popular culture, this paper provides a novel perspective for understanding immigrant identity and outlines directions for future research.
