As opposed to the classic four-part subject symphony construction, I Symphony has three movements. The first part is preceded with the slow introduction Lento sostenuto, played on cor anglais. The second part of Allegro has a folk character of Kurpie region.
The second movement – Largo pesante – takes from old polyphonic forms with features of Canzona and Passacaglia. Its first part emerges slowly, played by cellos and double bases and later develops into polyphonic style with developed dynamic. It ends with a contrasting pianissimo.
The third part starting immediately after the second movement unites jolly features of the missing in this symphony scherzo with rondo. The lively character of the finale gives the composer the opportunity to explore Polish folk melodies. The optimistic stretto closes the piece.
