This is a group of male singers with counterparts in other parts of Spain, including Andalusia itself, and Murcia. Miguel Angel Berlanga explains that "Campanilleros” have been popular in Andalusia ever since the Dominicans introduced them in the eighteenth century, linked to the worship of the Rosary of the Aurora (Dawn). In Bormujos, unlike several other areas in Spain where these groups are exclusively male, some women had begun to join them even before Lomax's visit, as evidences by these recordings. The singers accompany themselves on typical small percussion instruments; according to the tape box: "three handbells, a triangle, and a jar of which the mouth is struck with an alpargata to make the bass." This is also found in other parts of Spain: a clay jug or cántaro struck with some form of soft shoe, traditionally the straw-soled "alpargata." The field log also lists castanets, friction drum (zambomba, which Lomax spelled in the Catalan way, ximbomba), and guitar.
