0:01-0:48 Entry and rule

• The structure begins with a short cleared space, then one exposed vocal line.
• There is no accompaniment to divide the form from outside. The first rule is internal: rise, hover, return, breathe again.

0:48-2:24 Phrase cycles

• By 0:48 the chant has taught the listener how it will move.
• Each phrase repeats the ascent-and-return contract with small changes of angle, length, and pressure.
• Around 1:36 and 2:24, the form grows by recurrence rather than by contrast.

2:24-4:00 Middle endurance

• The middle span does not behave like a new section in a modern song.
• It deepens the same exposed line until tiny contour changes feel structural: a longer hold, a narrower descent, a warmer return.

4:00-5:35 Practiced return

• Around 4:00, repetition becomes the form's discipline.
• The return at 4:47 and the higher exposed region around 5:35 make the listener hear how much weight a small release can carry after so much suspension.

5:35-7:59 Withdrawal

• The final span keeps the same law but starts to thin its force.
• Near 7:11, the line prepares the room for ending rather than for another full cycle.
• The terminal silence around 7:52 is the last structural event: not an interruption, but the completed withdrawal of the line.
