Communication challenges (CCs)—including conditions such as aphasia, stuttering, hearing loss, Parkinson’s disease, and breathing disorders—affect millions worldwide and can severely impact social participation, emotional well-being, and quality of life. Traditional interventions often focus on clinical symptoms, but there is increasing recognition of the value of complementary approaches that also address psychosocial needs. This chapter explores the potential of group singing as a low-cost, scalable intervention for people living with CCs. Drawing on findings from the literature, we outline how singing can improve breath support, voice strength, fluency, and communication confidence. Singing in groups also fosters social connection, emotional expression, and a sense of belonging. We review evidence across five communication challenges, highlighting both functional communication outcomes and psychosocial benefits. Inclusive, ability-focused choirs—designed with non-audition policies and accessible materials—offer opportunities for individuals to participate regardless of skill level. For many, this participation leads to a shift from a deficit-based identity (“I have a disorder”) to a strengths-based one (“I am a singer”). As the global burden of CCs grows, particularly in aging populations, community-based interventions like group singing may play an increasingly important role in supporting health, inclusion, and quality of life.
