Ethnic minority music is an important carrier of cultural diversity and national identity, playing an irreplaceable role in the formation and maintenance of regional ethnic identity and cultural diversity. It is not only an important component of ethnic minority culture, but also an important way for ethnic minority people to express emotions, pass down history, and maintain social relationships. By analysing the characteristics and forms of minority music communication, we can discover the role of music communication in the formation and maintenance of national identity. Music can not only convey emotions and thoughts, but also strengthen national identity and cultural self-confidence. In ethnic minority areas, music often becomes an important way for people to gather and communicate, which helps to enhance national cohesion and cultural heritage. Protecting cultural diversity is of great significance for maintaining world peace and promoting the progress of human civilization. By protecting and inheriting minority music, we can preserve the uniqueness and diversity of different cultures and promote cultural exchange and integration. Therefore, we should attach importance to the inheritance and development of minority music, providing more support and platforms for it.
