Mortuos Plango, Vivos Voco ("I Mourn the Dead, I Call the Living") for eight-track tape is a musical composition created in 1980 by Jonathan Harvey, with the assistance of Stanley Haynes and Xavier Rodet, commissioned by the Centre Georges Pompidou in Paris. The two sounds contrasted are the tenor bell at Winchester Cathedral, England and the voice of the composer's son Dominic, at the time a chorister there, both recorded by John Whiting. The text is taken from that written on the bell: Horas Avolantes Numero, Mortuos Plango: Vivos ad Preces Voco ("I count the fleeing hours, I lament the dead: the living I call to prayer"). Music V was used to analyze and transform the sounds.
