The work is very playable. The work is in one movement which emphasizes a broad range of mood. Both instruments contribute equally to the work's content and expression.
Counterpoint is an almost constant feature.
The piece is built on three disparate moods which are introduced, then interwoven throughout the course of work. The first and opening section is coloristic and quiet with sustained tones, open strings and high harmonics. The haunting purity of sound begins to undulate in the second section. The rotation increases rapidly until, at the beginning of the third section, a quick-paced theme is introduced. The theme seems at once to be a natural result of the previous and also to be in striking contrast.
