Climate change has become an increasingly pressing issue, both to scientists and the public. While adults grapple with their own concerns, children are also experiencing eco-anxiety, and studies show that children seem to experience these levels of anxiety associated with environmental degradation and climate change at rates much higher than adults. The authors have a unique opportunity this year to study the effects of choral music on cognitive, affective, and behavioral development in children aged 10-18. For their 150th anniversary celebration in 2024, the Mendelssohn Chorus of Philadelphia commissioned a major choral piece about climate change and approached Commonwealth Youthchoirs to collaborate with the composer, Dr. Melissa Dunphy to bring the voice of children into the text. Our mixed methods research will document the effect of participating in this process—in the creative design, the learning of the music, and performance of the music—and how it may influence children's cognitive, affective, and behavioral relationship with climate change. In this presentation, we will share a preliminary model focusing on cognitive, affective, and behavioral domains that address education, eco-anxiety, and empowerment, and our in-process methodological approaches.
