His treatment of the 2nd and 3rd theme groups is completely new.
In the development Bruckner uses all methods of thematic elaboration: apart from harmonic and instrumental crescendos he applies all contrapuntal devices like augmentation, reduction, reversion and combination of several themes.
Recapitulation: the returning main theme is often enriched, otherwise the classical rules are observed.
Coda: By stressing the idea of the Coda, resp. the Finale the point of gravitation has shifted within the sonata form. The development is not so much a struggle (like the thematic elaboration in Beethoven's concept), it is rather a further symphonic growth. The climax is shifted from the development towards the Coda.
2nd movement: Bruckner is the creator of the most solemn Adagios. The soul of the mystic who has had a vision of God reveals itself. Bruckner's symphonies are "non-verbal Masses" - a thought that strikes you on listening to his 2nd movements.
3rd movement: they contain elements from popular dances of his Upper Austrian home province (Ländler, "G'strampfte").
