[Instrumental Break] (piano writes a precise three-note figure, regular spacing, almost mechanical) [Interlude] (low cello interrupts; piano restarts at once, leaving the reply unfinished) [Build-Up] (five short piano phrases grow denser; viola presses beneath the repeated pattern without joining it) [Break] (the closing piano chord meets a low dissonance; one brief failed restart, abrupt stop) [End] [Instrumental Break] (oboe searches through gaps in the three-note piano figure, no tonic landing) [Interlude] (cello answers the piano; their phrases lean closer, spacing grows less exact) [Build-Up] (a small rising figure catches between cello and oboe; piano repeats it more lightly, briefly buoyant) [Break] (the instruments return to separate registers; a low piano question leaves an open beat) [Outro] (oboe repeats the question with its last note missing; quiet unresolved room decay)
