In 2010, UNESCO classified Western Armenian as a “definitely endangered” language, highlighting the need for language revitalization in Armenian diaspora communities. This research examines a community-centered approach to revitalizing Armenian heritage language through the integration of folk songs that remain active in modern-day Turkey, Armenia, and diaspora communities worldwide. Many of these songs are preserved in Western Armenian dialects such as Hamshen, Gyumri, and Akhalkalak. Hamshen folk songs, now republished in contemporary musical formats like Black Sea Rock, increase their relevance and accessibility for younger generations. Folk songs, being communal, offer a supportive environment for diasporic Armenians to reconnect with their heritage language, helping to counteract the insecurity that often hinders language use. Research by Salcedo (2002) and Engh (2013) shows that language acquisition thrives in low-anxiety environments, and music can lower emotional barriers, enhance vocabulary recall, and improve pronunciation. Folk music’s deep connection to heritage language reinforces cultural identity, making it a key element in diaspora language education. This research includes ethnographic fieldwork conducted between October 2025 and March 2026 in various diaspora communities, participatory action research through folk singing workshops in diaspora communities, and analysis of interviews with the diaspora’s older generations and music educators, and performances. It uses frameworks from ethnomusicology, heritage language education, and affective theory in second language acquisition to explore how musical participation fosters linguistic confidence and emotional ties to Armenian identity. Ultimately, folk song practices in diaspora communities can serve as vital tools for sustaining Armenian heritage language and fostering a sense of collective belonging.
