How was the use of percussion revolutionary in the rite of spring?

In Igor Stravinsky's "The Rite of Spring," the use of percussion was revolutionary because it shifted the focus from traditional melodic structures to rhythm as the driving force of the music. Stravinsky employed an expanded percussion section with unconventional instruments, creating complex layers of rhythm that intensified the work's primal themes. This emphasis on rhythm over melody challenged contemporary musical norms and contributed to the piece's powerful, visceral impact, ultimately influencing the course of 20th-century music. The result was a radical reimagining of orchestral sound that highlighted the raw energy and chaos of the narrative.
