A virtual choir, online choir or home choir is a choir whose members do not meet physically but who work together online from separate places. Some choirs just sing for the joy of the shared experience, while others record their parts alone and send their digital recordings, sometimes including video, to be collated into a choral performance. There may be a series of rehearsals which singers can watch online, and their performance recordings may be made while watching a video of the conductor, and in some cases listening to a backing track, to ensure unanimity of timing. The worldwide COVID-19 pandemic in 2020 inspired a large growth in the number of virtual choirs, although the idea was not new.
