 The woodwinds and brass play harmonic fragments, often juxtaposing major thirds in a high register above the darkly dissonant harmonic texture.All this energy culminates in a huge fugato (based on material already present), marked ‘Intensivo’, which breaks away from the harmonic field.The texture is now more contrapuntal and polyphonic, and a fortissimo dynamic is maintained for several minutes, after reaching a final crushing dissonance, the music fades away to a single mysterious line doubled in the cellos and basses, which acts a transition into Part Two of the symphony, a central Adagio.
