Immensely influential, the remarkable Symphonie fantastique was composed while Hector Berlioz was suffering an intense and unreciprocated passion for the Irish actress Harriet Smithson. It's autobiographical tale describes a young musician's opium-poisoned nightmares of jealous despair and fatal justice following the murder of his beloved. Berlioz wrote a second movement cornet solo into a subsequent revision of the score, here included as an optional extra. He wed his sweetheart actress but, recuperating in Nice, wrote Le corsaire after the final breakup of their marriage.
