Music often facilitates the experience of communitas within disparate groups of people. As the American mainline Protestant church faces schism and struggles for relevance in a post-modern era defined by mistrust in the institutional church and social subjectivism, reexamining how singing together can break down barriers within ecclesial structures and create shared understanding is merited. As demonstrated through the music of pilgrimage, community musicking allows individuals to define the sacred together. Music then becomes an educational resource for the reformation of the church. The Iona and Taizé communities offer insights into this process. Their publishing efforts and worship styles, influenced and crafted by the populations who visit their locations, have provided resources for this dialogue in localized contexts. However, the experience of communitas is individualized—no one person, group, or organization can define this outcome. Consequently, no single musical or liturgical approach will be appropriate in all contexts; the church’s music must adapt so that each selection is imbued with meaning for that community. Facilitating such a process in the local congregation may threaten the status quo while also becoming a tool for revitalization in the post-modern era.
