Social distancing measures that were mandated or voluntarily adopted during the COVID-19 pandemic inevitably impacted the activities of all musicians, especially those who perform for live audiences and those who gather in groups to make music. Early in the pandemic, music ensembles made headlines following several “superspreader events” that took place at choir rehearsals ^[1][2][1,2]. The risk undertaken by singers was scrutinized most closely, given their reliance on breath for sound production and their habit of performing in close proximity to one another using resonant indoor spaces ^[3][4][3,4]. Emphasis was placed on the dispersal of aerosols and droplets, which also accompanies sound production in wind instruments ^[5][6][5,6]. While various in-person mitigation strategies were proposed ^[7][8][7,8], most choral ensembles ultimately adopted virtual approaches to rehearsing and performing [9]. Other collaborative and performing musicians likewise turned to the internet as the most viable means of sustaining their practices. This entry will consider the full range of pandemic impacts on participatory musicians in particular, focusing on their uses of the internet to play and sing together.
