Julio Iglesias songs used to 'torture' prisoners in Pinochet regime Others said they used music to pluck up courage ahead of torture as two ex-inmates recalled listening on a pocket radio to Harry Nilsson's Without You, Alone Again by Gilbert O' Sullivan and Morning Has Broken by Cat Stevens. Many prisoners sang, sometimes secretively, and in the less violent camps they were able to play musical instruments and put on shows, said the Chilean researcher. Dr Chornik is also researching the revival of a choir formed in Tres Alamos, Santiago, one of the largest camps for political prisoners. The camp's authorities gambled the effort would improve its image, particularly as they were expecting an inspection of the Organisation of American States' human rights commission, she said. Dr Chornik said: "Music brought prisoners together because it was a way to deal with their terrible suffering. But music was also a form of testimony. Many prisoners did not officially exist, so many were to disappear without trace and songs were a way of remembering who they were and what they believed in. Pinochet's system also used music to indoctrinate detainees, as a form of punishment and a soundtrack to torture. Played at intensely high volumes for days on end, the otherwise popular songs were used to inflict psychological and physical damage. Dr Chornik is conducting a project, funded by the Leverhulme Trust, called Sounds Of Memory: Music And Political Captivity In Pinochet's Chile.
