Boyobi
The video clip below shows Louis Sarno talking about recording Bayaka Boyobi ceremonies, and is part of a series of video interviews with Louis that were recorded in April 2012.
Boyobis are Bayaka ceremonies that are often performed before net hunting. Women sing interlocking webs of polyphonic sound to entice the bobé spirits out of the rainforest and bless the forthcoming hunts. Bobé spirits can sometimes be heard speaking in distinctive voices, singing motifs and encouraging the choirs.
In the playlist below, recordings from several different boyobi ceremonies show some of the different sections, including polyphonic singing, the sounds of bobé spirits addressing and haranguing the group, and sometimes blessing the ceremony with their symbolic spit.
