How did Luigi Russolo's intonarumori reflect Futurist ideas about industrial society?

Luigi Russolo’s intonarumori (noise instruments) were a direct manifestation of the Futurist movement’s core philosophy, which sought to discard traditional artistic values in favor of celebrating the dynamism, speed, and power of the modern machine age.123

In 1913, Russolo proposed that traditional music be abandoned entirely, arguing that the sonic landscape of an industrialized society required new instruments capable of expressing the realities of modern life. His intonarumori were designed to produce sounds that mimicked the mechanical environment—grating, hissing, scratching, rumbling, and shrieking—thereby aligning musical expression with the aggressive, restless energy of early 20th-century urban and industrial existence.32

By creating these noise-generating machines, Russolo embodied the Futurist demand for innovation and the rejection of cultural institutions, attempting to replace conventional musical aesthetics with a raw, technological soundscape that reflected the intensity of the machine era.123
