Which characteristic is NOT typically associated with impressionist composers?

The choice that is not typically associated with impressionist composers is the emphasis on melodies centered around strong rhythmic patterns. Impressionist music is characterized by a departure from traditional forms and structures, focusing instead on fluidity, atmosphere, and subtle nuances. This genre often features ambiguous harmonies, rich orchestral color, and a focus on texture rather than on firm and pronounced rhythms.

In contrast to the strong rhythmic patterns found in other musical styles, impressionist composers like Debussy and Ravel often employed more flexible and flowing rhythms, which allows the listener to experience a sense of dream-like exploration rather than a driving beat. This approach enables the music to evoke visual images and emotions, aligning with the overall aesthetic of impressionism. Thus, strong rhythmic patterns do not align with the typical characteristics found in impressionist compositions.
