In this article, I introduce insights from new material feminist theories into the understanding of connectivity on the basis of an aesthetic analysis of artistic encounters with people living with dementia. I draw on data from a situated art intervention conducted within the Resonance Project at a residential care home in Northern Norway where researchers, artists, health-care professionals, people living with dementia and family members came together in co-creative music sessions. I analyse two resonating moments from the sessions by way of an abductive process, oscillating between theory, written notes, video recordings and my own embodied experiences in the field. I discuss the ways in which materiality, listening and the group matter when it comes to our ability to connect during the sessions. Based on these findings, I conclude that the notion of socio-material connectivity provides an entrance point for studying different ways of relating to people living with dementia and enquiring into relations that matter.
