Childhood trauma is a pervasive phenomenon with life-long consequences impacting an individual's physical, psychological, and social-emotional well-being. Students who have experienced trauma often struggle with the regulation of emotions, however, researchers have noted that music can be a helpful tool in emotion regulation. Music educators can support students in the development of social and emotional competencies, including students who have experienced trauma, through Social Emotional Learning (SEL). There is limited research on SEL in the context of music education, particularly in the context of elementary general music. Therefore, the purpose of this study was to explore the ways in which elementary general music educators incorporate Social Emotional Learning (SEL) into their music instruction. For this multiple-case study, I recruited three elementary general music educators who had (a) a minimum of three years of experience teaching elementary general music in a public or private elementary school setting, with at least two years of experience working in their current school, and (b) currently worked to incorporate SEL into their elementary general music instruction. I conducted three semi-structured interviews with each participant over the span of two months. Analysis of the data revealed several themes, including preparation to incorporate SEL, COVID-19, lesson planning, reasons to incorporate SEL, and challenges incorporating SEL. The results of this study may have implications for pre- and in-service music educators. In-service music educators might benefit from personalized professional development addressing various facets of SEL and its application to elementary general music settings. Music teacher educators might consider embedding SEL practices into their pre-existing curricula to ensure that pre-service music educators receive explicit instruction in SEL prior to entering the teaching field.
