Symphonies that Berlioz would have known, including Beethoven’s and those of his predecessors, usually included a dance movement (the Minuet and Trio) or, especially with Beethoven, the faster movement known as ‘Scherzo’, usually placed third after a slow movement. Having decided to put the slow movement third, Berlioz replaces the Minuet or Scherzo with a waltz. He evokes the glitter of a ballroom by introducing harps to the orchestra. The idée fixe suggests that the beloved woman is there; it is transformed to fit the waltz rhythm, acting as a contrasting section and reappearing near the end. Berlioz added a brilliant coda when rewriting the whole movement from scratch during his stay in Italy (1831–2).
