Narration sentence highlighting is idle.

The piano comes in from silence with a line that feels close and intimate.

The left hand settles into its ground, and a singing melody starts to move above it.

Same shape, deeper shade. The harmony has darkened on this return.

The ornaments are getting more insistent now. The melody keeps reaching forward and pulling back.

There's a weight building here that has nothing to do with volume. Chopin keeps returning to the same phrase, and each time there's more gathered behind it.

The texture starts easing back. The melody's still there, but it's pulling away from all that weight.

The piano comes back with more exposed brightness. Same lyrical shape, but the upper notes feel less sheltered now.

The pattern is here again, but each phrase leans harder into its descent. Nothing feels quite as settled as before.

Small ornamental turns keep flashing through. The pulse holds, but the surface won't settle.

The grip starts loosening. The piano lets the phrases thin out and drift toward resonance.

The last gestures don't solve anything. They just let go.
