Some Stanford University undergraduates made a brief documentary on the Bay Area Sacred Harp singing community. The students were in an ethnomusicology class, and their goal was to document a local musical community. Given their time constraints, I think they give a pretty good sense of how music and community are woven together in Sacred Harp.
Notes: No one is identified in the video, but this is who you’ll hear from, in order of appearance: Pat Coghlan, Gridley, Calif.; Lena Strayhorn, San Francisco; Jeannette Ralston, Half Moon Bay; Terry Moore, Palo Alto. (Jeannette is the senior singer who was interviewed; she has been singing Sacred Harp in the Bay Area since the 1970s.) The local singings shown are Berkeley (in the church with pews); Palo Alto (in the children’s art room); and San Francisco (in the living room). You’ll hear the Palo Alto singers on Nehemiah Shumway’s Ballstown (begins 0:05; cont. 0:27 and William Billings’s Easter Anthem (begins 1:58).
