Allegro giusto, A minor, 4/4 time. Sonata form. It begins with a dark and eerie theme, and the entire movement is dominated by a motif that, when attempting to ascend, seems to pull one downwards. Furthermore, contrasting elements such as unisons and thick chords, long notes and dotted rhythms, and disjunct motion alongside repeated notes and conjunct motion coexist, forming a dramatic movement.
