Berlioz, the son of a French doctor, was influential in the fantastic movement. He wrote the Symphonie Fantastique about an actress he was in love with. It is a program symphony about his unrequited love involving an opium trip and his death. The final movement captures the "fantastic" with supernatural, impossible, and difficult to comprehend references to witches and death. There is a recurring theme known as an idee fixe that is meant to represent the love interest.
