0:00-1:30 Poise and rule

• The opening sets the structural rule: a poised statement, a return, and a pulse that carries without forcing.
• The form begins by asking the listener to hear consequence inside restraint.

1:30-4:13 Altered returns

• The early material comes back with different harmonic light rather than simple repetition.
• Each phrase lands like a ledge: stable enough to stand on, narrow enough to require another path.

4:13-8:00 Larger lift

• The first broader rise makes the phrases pull on one another.
• Structure turns grace into risk by keeping the pulse steady while the accents and weight lean across it.

8:00-10:38 Mechanism forming

• The loosened return prepares the piece for tighter motion.
• From about 9:58 to 10:38, interlocking figures create a lattice span: forward motion made from precision, delay, and recurrence.

10:38-13:53 Stored patience spent

• The later passages convert the earlier poise into pressure.
• By roughly 12:43 the final lattice span has arrived; the structure is now speed held inside exactness.

13:53-14:05 Cut into silence

• The ending breaks the motion rather than explaining it.
• Terminal silence becomes the last structural event because it carries the weight of everything the piece has stored.
