0:00-0:35 Opening blocks

• The piece starts with spaced piano blocks, not a sung-out theme.
• Each return lets resonance complete the phrase before the next step appears, so the opening structure is already built from sound and gap.

0:35-2:06 Return rule becomes architecture

• Around 0:35, the first clear internal pause confirms that silence is part of the form.
• The repeated harmonic steps grow broader without becoming busy; the structure rises by patient recurrence.

2:06-2:45 Central authority

• By 2:06, the main body has its firmest shape: slow pulse, large chords, and a strong sense of vertical mass.
• This is the piece's clearest emergence, where the title image becomes audible through form rather than description.

2:45-3:07 Release and reset

• Near 2:45, the central weight drains away in steps.
• The reset around 3:07 clears the ear for a second build, but the return feels more fragile than the first ascent.

3:07-4:04 Rebuild under disturbed water

• The pulse and repeated figures come back with more insistence.
• The form tries to recover its earlier authority, but now the listener hears the strain inside the recurrence.

4:04-5:36 Fragments and withdrawal

• At 4:04, the main hold loosens and the structure stops carrying attention by large blocks.
• The ending survives through partial returns, softened spacing, and long decay until withdrawal becomes the final form.
