Composed in 1912. The short introduction is striking, with a tritone, historically known as the "devil's interval," resounding thunderously. What follows, beginning with a dramatic descending leap, is a theme that is harmonically dissonant, rhythmically irregular, fragmented, rough, and develops unfettered in all directions.

The middle section clearly contrasts with the opening. In addition to being based on ascending scalar stepwise motion, it conveys a sense of breadth, depth, and emotion, which were absent in the opening, both rhythmically and harmonically.
