Music

Futurist music rejected tradition and introduced experimental sounds inspired by machinery, and would influence several 20th-century composers.

Francesco Balilla Pratella joined the Futurist movement in 1910 and wrote a Manifesto of Futurist Musicians in which he appealed to the young (as had Marinetti), because only they could understand what he had to say. According to Pratella, Italian music was inferior to music abroad. He praised the "sublime genius" of Wagner and saw some value in the work of other contemporary composers; Richard Strauss, Elgar, Mussorgsky, and Sibelius, for example. By contrast, the Italian symphony was dominated by opera in an "absurd and anti-musical form." The conservatory was said to encourage backwardness and mediocrity. The publishers perpetuated mediocrity and the domination of music by the "rickety and vulgar" operas of Puccini and Umberto Giordano. The only Italian Pratella could praise was his teacher Pietro Mascagni, because he had rebelled against the publishers and attempted innovation in opera, but even Mascagni was too traditional for Pratella's tastes. In the face of this mediocrity and conservatism, Pratella unfurled "the red flag of Futurism, calling to its flaming symbol such young composers as have hearts to love and fight, minds to conceive, and brows free of cowardice."

Luigi Russolo (1885–1947) wrote The Art of Noises (1913), an influential text in 20th-century musical aesthetics. Russolo used instruments he called intonarumori, which were acoustic noise generators that permitted the performer to create and control the dynamics and pitch of several different types of noises. Russolo and Marinetti gave the first concert of Futurist music, complete with intonarumori, in 1914. However, they were prevented from performing in many major European cities by the outbreak of war.

Futurism was one of several 20th-century movements in art and music that paid homage to, included, or imitated machines. Ferruccio Busoni has been seen as anticipating some Futurist ideas, though he remained wed to tradition. Russolo's intonarumori influenced Stravinsky, Arthur Honegger, George Antheil, Edgar Varèse, Stockhausen and John Cage. In Pacific 231, Honegger imitated the sound of a steam locomotive. There are also Futurist elements in Prokofiev 's The Steel Step as well as his Second Symphony.

Most notable in this respect, however, is American artist George Antheil. His fascination with machinery is evident in his Airplane Sonata, Death of the Machines, and the 30-minute Ballet Mécanique. The Ballet Mécanique was originally intended to accompany an experimental film by Fernand Léger, but the musical score is twice the length of the film and now stands alone. The score calls for a percussion ensemble consisting of three xylophones, four bass drums, a tam-tam, three airplane propellers, seven electric bells, a siren, two "live pianists," and sixteen synchronized player pianos. Antheil's piece was the first to synchronize machines with human players and to exploit the difference between what machines and humans can play.
