0:00-0:26 Opening — step and theme established at once

• Timpani pulses begin in near-silence; around 0:04 the brass enters with the main march melody, so the pulse and the theme arrive as a single gesture.
• The motif restates and gathers to a full-orchestra peak near 0:20. This span sets the terms: a stern step and a theme stated plainly enough to be recognized on every return.

0:26-0:52 First extension — widens, then thins

• Strings join near 0:24, answering the brass, and the ensemble swells toward a transitional peak around 0:36.
• Just past 0:40 the scoring abruptly reduces to low strings and low brass carrying a brooding variation of the theme, with chimes and high strings floating above it by the late 0:40s.
• The phrase eases and drops back at 0:50–0:52 — the form narrows here rather than resolving.

0:52-1:41 Rebuild and full refrain — the march reloads

• Horn calls over urgent string tremolos gather through the late 0:50s; the march step re-establishes in low brass around 1:00.
• A restless secondary line in woodwinds and high brass delays the payoff until the full theme re-enters near 1:12.
• Stated twice with swirling string countermelodies, peaking around 1:28, the refrain proves itself at full force before a short fanfare bridge near 1:32.

1:41-2:02 Middle span — the theme withheld

• Muted brass, a marching snare figure, and winding woodwind lines replace the melody; the step continues while the refrain withdraws.
• The repetition does new work: pulse without theme, holding the march in reserve.

2:02-2:33 Return — the march restored

• The full march re-forms around 2:02, theme and step together again; the return itself, not new material, is this section's job.
• The statement gathers in stages toward a final push rather than peaking early.

2:33-3:05 Final statement and close

• From 2:33 the last full statement settles onto the steadiest footing of the performance, the theme driven home without additions.
• The final phrase drops at 2:51; closing chords land near 2:54, the sound lets go, and the decay fades into silence by about 3:01 — a full stop rather than a dissolve.
