March to the Scaffold
"Songe d'une nuit de sabbat" (Dreams of a Witches' Sabbath)Convinced that his love is unappreciated, the artist poisons himself with opium. The dose of narcotic, while too weak to cause his death, plunges him into a heavy sleep accompanied by the strangest of visions. He dreams that he has killed his beloved, that he is condemned, led to the scaffold and is witnessing his own execution. As he cries for forgiveness the effects of the narcotic set in. He wants to hide but he cannot so he watches as an onlooker as he dies. The procession advances to the sound of a march that is sometimes sombre and wild, and sometimes brilliant and solemn, in which a dull sound of heavy footsteps follows without transition the loudest outbursts. At the end of the march, the first four bars of the idée fixe reappear like a final thought of love interrupted by the fatal blow when his head bounced down the steps.
He sees himself at a witches' sabbath, in the midst of a hideous gathering of shades, sorcerers and monsters of every kind who have come together for his funeral. Strange sounds, groans, outbursts of laughter; distant shouts which seem to be answered by more shouts. The beloved melody appears once more, but has now lost its noble and shy character; it is now no more than a vulgar dance tune, trivial and grotesque: it is she who is coming to the sabbath ... Roar of delight at her arrival ... She joins the diabolical orgy ... The funeral knell tolls, burlesque parody of the Dies Irae, the dance of the witches. The dance of the witches combined with the Dies irae.
