Page "A Clockwork Orange" Paragraph 4

Sentenced to prison for murder, Alex gets a job at the Wing chapel playing religious music on the stereo before and after services as well as during the singing of hymns.

The prison chaplain mistakes Alex's Bible studies for stirrings of faith ( Alex is actually reading Scripture for the violent passages ).

After Alex's fellow cellmates blame him for beating a troublesome cellmate to death, he agrees to undergo an experimental behaviour-modification treatment called the Ludovico Technique.

The technique is a form of aversion therapy in which Alex receives an injection that makes him feel sick while watching graphically violent films, eventually conditioning him to suffer crippling bouts of nausea at the mere thought of violence.

As an unintended consequence, the soundtrack to one of the films — Beethoven's Ninth Symphony — renders Alex unable to listen to his beloved classical music.
