Inner Mongolian wedding folk songs are vital to the region's intangible cultural heritage, reflecting the Mongolian people's history, values, and traditions. This study investigates music literacy in the preservation of Inner Mongolian wedding folk songs. Utilizing a qualitative ethnographic approach, the research focuses on the Inner Mongolia Autonomous Region, examining the integration of wedding folk songs into educational curricula to ensure their survival amidst globalization and urbanization. Data were collected through interviews with three key informants: scholars, folk musicians, and cultural practitioners, observations of wedding ceremonies, and document analysis. The findings underscore the critical role of music literacy in documenting, transmitting, and adapting these songs to contemporary contexts while maintaining their authenticity. Challenges such as generational disconnect, limited resources in rural areas, and declining Mongolian language proficiency were identified. Collaborative efforts between educators, musicians, and policymakers have shown promise, with instructional materials and digital archives enhancing accessibility and engagement. The study concludes that a multifaceted approach, incorporating education, technology, and community involvement, is essential for preserving Inner Mongolian wedding folk songs. Future research should focus on digital innovations, bilingual education, and strategies to engage younger generations in cultural preservation.
