Narration sentence highlighting is idle.

High notes enter alone, soft and lightly struck.

A low pedal wash gathers under the moving line.

The phrase crests, then settles into quiet sustained resonance.

Upper notes ring clear against the warm low tone.

A soft left-hand pulse steadies under the long line.

The line stretches upward into a brighter peak, then eases.

Soft upward runs weave through the held pedal air.

Chordal weight arrives; the pulse sits heavier under the line.

Chords press more firmly as the accompaniment swells.

The piano reaches a full resonant crest, chords ringing hard into the room.

Intensity breaks into cascading descending figures.

Sound drops out—a brief held empty—then the piano re-enters softly.

The cascades thin to spaced single notes, still expressive.

The returning line keeps a quiet suspended field—no new weight, only soft continuation.

A last chord is held and begins its slow fade.

Only faint resonance remains in the room, then it is gone.
