0:00-0:35 Establishes the submerged frame

Soft solo piano sets the piece as spaced chordal statements and answering quiet. The short silences are part of the opening grammar: entries, resonance, withdrawal, continuation.

0:35-2:06 Enlarges the frame

The same slow materials return with more reach. Chords broaden, registers open, and the repeated pattern becomes more declarative without becoming a new kind of motion.

2:06-2:45 Opens into figuration

Flowing arpeggiated movement enters and carries the form forward. The piece shifts from tolling, block-like statements into a more mobile span, gathering toward its largest local weight.

2:45-4:04 Releases, then reloads

After the central crest, the sound thins and loosens. A brief reset around 3:07 does not end the argument; the pulse and chordal weight gather again, rebuilding the same formal contract rather than replacing it.

4:04-5:40 Returns in withdrawal

The opening world comes back with much less carrying force. Repeated breaks and soft re-entries make the return feel partial, as if the form is receding while still keeping its outline.

5:40-5:52 Withholds closure in decay

The final resonance gives way to silence. The ending closes by disappearance rather than by a hard cadence.
