This study originates from the researcher’s observations and investigation within community choirs in both China and the United States. While many studies have highlighted the positive impacts of choral participation on older adults, few have compared elderly singers’ participation, motivations, and reflections across the two countries, or examined the sociocultural differences underlying these experiences. Despite challenges, older adults in both countries display remarkable passion for music, which prompted further investigation into their motivations and the benefits of participation. A critical research gap was identified: limited attention has been paid to how educators and policymakers can address older adults’ unique needs in community music-making.Through a comparative case study of community choirs in Columbia, Missouri, and Chongqing, China, this research examines the participation, motivations, and reflections of retired choir members. Employing a qualitative phenomenological approach, the study draws on semi-structured interviews and observations to capture participants’ lived experiences.Findings reveal clear contrasts between the two contexts. In the U.S., motivations derive largely from early musical heritage, religious faith, and the pursuit of leisure and artistic fulfillment after retirement. In China, where religion plays a minimal role, participation is driven primarily by personal interest and amateur hobby. Ecological differences also emerged: most Chinese senior choirs are tied to government-affiliated senior universities, where bureaucratic oversight constrains autonomy; U.S. choirs, by contrast, emphasize diversity, equity, inclusion, and accessibility (DEIA). Nevertheless, common benefits were observed: intergenerational choirs provide cultural exchange, community engagement, and opportunities for social contribution; participation reduces depression and loneliness, enhances self-esteem, improves respiratory health, and enriches quality of life. Challenges such as vocal aging, reduced stamina, transportation issues, and social integration persist in both contexts, though participants often emphasized self-reliance over external assistance.The significance of this study lies in deepening understanding of how choral participation supports older adults’ physical, psychological, and social well-being, while revealing cross-cultural differences that shape these experiences. It also highlights the need for adaptive strategies in music education and choral practice to better meet the needs of older singers. By providing empirical evidence, this study aims to inform educators, conductors, and policymakers in fostering more inclusive and sustainable community music environments for older adults, and build the example for bridging choir culture between western and eastern system, in particular, it may serve as an inspiration for educators and policymakers.
