How did Igor Stravinsky change the use of rhythm and percussion in The Rite of Spring?

In The Rite of Spring, Igor Stravinsky revolutionized Western music by introducing a new rhythmic sensibility that departed from the traditional subdivision of regular groups. Instead, he treated rhythm as a cumulative process, building structures by adding together "sound objects" into varied groups.12

Stravinsky utilized asymmetrical metrical patterns and constant metric imbalances to break down the tradition of symmetrical phrasing. His approach was empirical; he experimented with musical material to challenge established practices, often using devices of prolongation and elision.12

Regarding percussion, the work is noted for its "percussive violence" and "barbaric tone colours," which served to emphasize this new rhythmic momentum. By rejecting the Germanic tradition of thematic development in favor of a sculptural approach, Stravinsky ensured that the rhythm and sonority—rather than just melody—became the primary drivers of the musical structure. This innovative use of rhythm and percussion created a sense of "primitive dynamism" that profoundly influenced how later composers approached pulse, rhythm, and form.23
