The present study employs a mixed methods approach to understanding the psychological functions and contexts of music use. Seventy-six emerging adults selected a single piece of music that they considered personally significant and elaborated on the reasons for this significance in response to written prompts. A constant comparative analysis of these retrospective accounts revealed three major themes. Specifically, participants selected music that helped them cope with a transition, facilitated self-reflection, or elicited positive memories. Additionally two metathemes emerged: participants selected music with lyrics that resonated with their own experiences or that helped them feel less alone. Quantitative analyses revealed systematic differences between the three major themes. Results are discussed in light of the psychological functions music may serve. (Contains 2 notes.)
