0:00-0:25 Rocking ground

The structure begins by establishing the motion that will govern the whole piece. Strings set down the rocking figure, and the first choral entrance grows from that floor rather than replacing it. The form's first job is to make the listener feel the repeated lift and fall as law.

0:25-0:50 Choral weight joins the mechanism

The voices enter as one body, and the structure becomes choral-orchestral instead of melodic with accompaniment. The phrases rise, bend, and return to the same ground. Each return feels less like a restart than another turn of the same mechanism.

0:50-1:21 Same gesture, more load

The middle build does not create a new room. It increases the weight carried by the existing gesture. The choir presses brighter, the orchestra thickens beneath it, and the form asks repetition to behave like escalation.

1:21-1:45 Loosening without escape

The pressure loosens around 1:21, but the structure keeps the rocking contract intact. This is not a contrasting episode in the usual relief sense. It is a narrowing of force inside the same ceremonial frame.

1:45-3:03 Long final carrying

The final long span turns recurrence into insistence. Phrases arrive in waves, and endings fold quickly into beginnings. The structure becomes severe because it refuses waste: every return keeps the listener inside the same suspended descent.

3:03-3:09 Motion spent

At 3:03, the pattern finally loses its task. The last cadence closes the choral body, then the terminal silence after 3:05 leaves the space that the rocking figure had been filling.
