Polirrítmico

Polirrítmico refers to the simultaneous use of two or more conflicting rhythms that are not readily perceived as deriving from one another or as belonging to the same metric framework. It is a compositional technique found in various musical traditions and contemporary music. Unlike polyrhythm, where the superimposed rhythms are typically related by a common divisor (e.g., 2 against 3), polirrítmico implies a greater degree of rhythmic independence and potential dissonance between the layers.

The effect of polirrítmico can create a sense of complexity, disorientation, or vibrant textural layering for the listener. Composers might employ it to achieve unique sonic textures, to create tension, or to explore the boundaries of rhythmic perception. The perception of polirrítmico is often subjective and can depend on the listener's familiarity with different rhythmic patterns and their ability to process multiple temporal streams. It is a technique that pushes beyond simple rhythmic layering into a more intricate and less predictable interplay of durations and accents.
