Keeping Score - Hector Berlioz Symphonie fantastique.

In 1827, Berlioz saw Harriet Smithson for the first time, playing Ophelia in a production of Hamlet. Hopelessly smitten, he turned his entire life upside down to meet her. Frantic months turned into years when he suddenly heard rumors about Harriet and another man. Believing himself cured, he wrote a ‘fantastic’ symphony complete with a special theme, the idée fixe, to represent his former obsession.
