What is the defining characteristic at the end of the excerpt from the Piano Sonata in C Minor?

The defining characteristic at the end of the excerpt from the Piano Sonata in C Minor is that it features dramatic and powerful chords. This conclusion typically embodies a sense of intensity and a strong emotional impact, which is consistent with the overall character of the piece. The sonata form often culminates in a climactic ending that utilizes bold, resonant chords to leave a lasting impression on the listener. This decisive and forceful conclusion reflects the dramatic narrative within the music and emphasizes the resolution of the preceding themes.

The other choices do not capture this intensity; soft and subdued chords would suggest a gentler conclusion, while a gentle fade-out implies a gradual dimming that lacks the forceful energy present at the end of this piece. Repeating motifs can indicate development but may not necessarily correspond to a powerful or dramatic ending in this context. Thus, the choice of dramatic and powerful chords effectively encapsulates the essence of the excerpt’s conclusion.
