Dilsey’s sombre, repetitive singing is reminiscent of the spirituals originally sung by black slaves during the antebellum era. These accompanied labour and were characterized by strong rhythm, improvisation, recurring patterns and overlapping call-and-response lines. The songs were both a communal expression of suffering under oppression and a means of alleviating its burden. Often they were underpinned by the affirmation of religious faith. In the 20th century, these songs had a profound influence on the music of blues singers.
