Futurism was an early 20th-century art movement which encompassed painting, sculpture, poetry, theatre, music, architecture, cinema and gastronomy. Filippo Tommaso Marinetti initiated the movement with his Manifesto of Futurism, published in February 1909. Futurist music rejected tradition and introduced experimental sounds inspired by machinery, and influenced several 20th-century composers. According to Rodney Payton, "early in the movement, the term ‘Futurism’ was misused to loosely define any sort of avant-garde effort; in English, the term was used to label a composer whose music was considered ‘difficult.’[1]"
