Six Families of Noises for the Futurist Orchestra
Russolo sees the futurist orchestra drawing its sounds from “six families of noise”:[5]
- Roars, Thunderings, Explosions, Hissing roars, Bangs, Booms
- Whistling, Hissing, Puffing
- Whispers, Murmurs, Mumbling, Muttering, Gurgling
- Screeching, Creaking, Rustling, Humming, Crackling, Rubbing
- Noises obtained by beating on metals, woods, skins, stones, pottery, etc.
- Voices of animals and people, Shouts, Screams, Shrieks, Wails, Hoots, Howls, Death rattles, Sobs
Russolo asserts that these are the most basic and fundamental noises, and that all other noises are only associations and combinations of these.
