The introduction (mm. 1–10), marked ♩= 80, establishes a powerful mood for the main body of the work. The introduction employs the full resources of the ensemble with most marked with a fully-articulated fortissimo.
Section 1 (mm. 11-62), marked ♩= 160, is highly energized. It has relentlessly-driving eighth notes providing forward momentum, contrasted by more sustained lines. All ensemble members will have responsibility for both the pulsing eighth note and the sustained lines.
Section 2 (mm. 63–107) offers a mood change, though at the same tempo. This section begins in a soft, reflective state. It is characterized by a slow melody in half and whole notes in the woodwinds layered over rhythmic eighth notes in the piano. The quarter notes in the mallets support the motor in the piano. The second half of this section (starting at m. 86) follows a gradual crescendo, adds the full ensemble, and presents a full-bodied restatement of the earlier woodwind presentation, descending in tessitura and dynamically away from the apex (m. 96), returning to the reflective mood.
Section 3 (mm. 108–162) returns to the earlier energized music after reestablishing the pulsating eighth notes. Material from the second section comes back at measure 146, this time full with firm articulation.
A short coda (mm. 163–181) finishes the piece in full voice with full instrumentation.
