Singers from community choirs in the UK and Norway participated in research to evaluate their experiences of singing in a collaborative choral event in the UK in June 2023. They shared personal stories of their participation and interpreted the significance of their experiences through the app-based data collection method Sensemaker®. We found strong evidence of fast social bonding through a shared emotional experience, which was amplified by the aesthetic qualities of the singing, the material qualities of the venue and the ethical qualities of leadership to model and express the values and attitudes underpinning the reported positive effects. As an intercultural activity, we found that both bonding and bridging social capital were produced through the activity, highlighting the potential of group singing as a potent form of civic imagination and for developing intercultural empathy. The study also highlights the value of practitioner enquiry as a research methodology for developing an understanding of the complex ways in which participation in cultural activities can lead to positive outcomes for participants.
