0:00–0:20 Establishes the lento alone

• Piano opens with heavy descending rolled chords and low pedal sustain, staking the maestoso weight before any string voice appears.

0:20–1:29 Gathers the lament into trio

• Solo cello enters on a slow expressive line; violin joins above it.
• Piano returns beneath the strings. The ensemble swells, crests, and eases through quieter interludes toward a suspended fermata that clears the frame.

1:29–1:53 Breaks into dance speed

• Tempo jumps into a lively folk allegro—rhythmic piano with traded, articulated string figures—then drives a punchy cadence that cuts the pace back.

1:53–4:28 Returns the lento and holds

• The slow majestic theme re-enters with heavy piano and solemn cello; violin soon harmonizes high.
• The long span keeps that contract: singing strings over piano support, local swells and releases inside one sustained slow field, without another tempo rupture.

4:28–4:31 Empties into silence

• Motion loses its hold; the final chord decays into room silence.
