Mixed meter is a musical term that refers to the use of two or more different time signatures within a single piece of music. This technique allows composers to create varied rhythmic patterns, enhancing the expressiveness and complexity of the composition. For example, a piece might alternate between 4/4 and 3/4 time signatures, creating a unique listening experience. Composers like Béla Bartók and Stravinsky often employed mixed meter to challenge traditional rhythmic structures. By shifting between meters, they could evoke different emotions and maintain listener interest. Mixed meter is commonly found in various genres, including jazz, classical, and progressive rock.
