What feature is often obscured in impressionistic music, as part of its unique style?

In impressionistic music, the obscuring of the metric pulse is a defining characteristic of the style. Composers affiliated with this movement, such as Claude Debussy and Maurice Ravel, often favored fluidity over strict rhythmic patterns. This results in a sense of ambiguity in the music, where traditional expectations of meter and beat are transformed or even eliminated. The focus shifts from clear rhythmic delineations to a more atmospheric and dreamlike quality, which is often complemented by rich harmonies and nuances in timbre.

This departure from a pronounced metric pulse allows for greater freedom in expression and interpretation, enabling musicians to explore textures and colors in their playing. The absence of a strong, regular beat contributes to the impressionistic effect of creating a specific mood or feeling rather than adhering to a clear structure or narrative.
