Dark-fantasy orchestral opener in a relentless 3/4 waltz from bar one. Celesta fires jagged arpeggios, low strings drive nonstop tremolo and col legno, bass trombones and contrabassoons stack dissonant chords, and timpani pound with subterranean force. Rapid violins cut the melody; gritty male lead, bell-clear female harmonies, bold bassline, and ghostly choir layered with wide hall reverb.
