Opening, then theme takes hold (0:00–0:58)

• A prepared silence gives way to low sustained strings.
• The recurring rhythmic figure enters gently, then repeats through short withdrawals and re-entries.
• By about 0:56, the movement has narrowed into its governing pattern rather than opening a new episode.

Main span: repetition expands (0:58–3:16)

• The pulse settles and the theme becomes the movement’s anchor.
• Strings carry the tread while higher lines and then woodwinds broaden the phrase space.
• The section does not pivot by sharp contrast; it proves the pattern through layered returns and gradual widening.

Continued development: the frame thickens, releases, and keeps working (3:16–5:43)

• The same pattern remains active, but phrase drops and renewed entries make the repetition sectional rather than static.
• Around 4:21, 4:44, and 5:19, the music settles into clearer stretches of carried motion.
• The long span presses the material forward until it begins to thin into the reset near 5:43.

Reset and reload (5:43–6:20)

• A longer gap suspends the motion without fully abandoning the movement’s identity.
• The return at about 5:55 reloads the pulse in a more precise, interlocking form.
• This is a hinge: not a new theme so much as the pattern re-entering with its parts more exposed.

Late return and closing withdrawal (6:20–8:40)

• From about 6:20, the movement returns to carried motion, gathering through another extended pass.
• After 7:42, the form begins to release in stages: short breaks, softened re-entries, and increasingly separated fragments.
• By 8:33 the hold loosens, and the final silence at 8:37 closes the movement by decay rather than a forceful cadence.
