Edgard Varèse

Varèse’s central idea was that composition could organize sound in space as well as in time. Born in Paris and raised partly in Burgundy, he studied at the Schola Cantorum and the Paris Conservatoire before working in Berlin, where he encountered the music of Richard Strauss, Ferruccio Busoni, and Arnold Schoenberg.¹ He moved permanently to the United States in 1915 and became an American citizen in 1926. His career was interrupted by financial hardship, limited performance opportunities, and the destruction of several early scores, yet he remained committed to finding new instruments and new acoustic resources.

Varèse rejected the description of his music as merely “atonal.” He preferred to speak of organized sound, sound masses, and moving planes of intensity. This language connected his work to modernist painting, architecture, and the emerging possibilities of recording and electronic technology.

Varèse’s mature reputation rests on a small but unusually influential body of works. Amériques (1918–21, revised 1927) uses a large orchestra, sirens, percussion, and abrupt contrasts to evoke the scale and energy of modern urban life. Hyperprism (1922–23), Octandre (1923), and Intégrales (1924–25) concentrate on sharply differentiated instrumental colors and rhythmic blocks.²

Ionisation (1929–31), written for thirteen percussionists, is a landmark of twentieth-century music because it makes percussion ensemble sound—not accompaniment—a complete compositional medium. Density 21.5 (1936) exploits the distinctive resonance of a platinum flute. Later works include Déserts (1950–54), which alternates orchestra with sections for recorded electronic sound, and Nocturnal (1961), left incomplete at his death.

Electronic technology gave Varèse the timbral freedom he had sought throughout his career. The first version of Déserts juxtaposes live orchestral episodes with tape-manipulated sounds, making its 1954 Paris premiere a controversial early event in electronic concert music.³ In 1958, Varèse created Poème électronique for the Philips Pavilion at the Brussels World’s Fair, designed by Le Corbusier with an electronic installation by Iannis Xenakis. The approximately eight-minute work was projected through hundreds of loudspeakers as visitors moved through the pavilion, turning architecture into part of the musical experience.⁴

Varèse’s influence extended to composers such as Pierre Boulez, Karlheinz Stockhausen, and John Cage, as well as to later electronic, spectral, and experimental traditions. His importance lies less in the quantity of his output than in the precision and boldness of his questions about what could count as musical sound.

Varèse’s surviving catalogue is only a fragment of his ambitions. Several early orchestral works, including Bourgogne, were lost or destroyed, and the composer’s repeated revisions make dates and versions significant when discussing pieces such as Amériques.¹ His interest in science was also unusually concrete: he followed developments in acoustics, communications, and instrument design, and he imagined compositions using sounds unavailable from traditional orchestras.

His percussion writing was not simply a search for noise. Varèse carefully differentiated resonance, attack, duration, and register, often combining conventional instruments with sirens, anvils, tam-tams, and other objects. The title Density 21.5 refers to the density of platinum, the material of the flute for which the piece was written. The Varèse International Center, established after his death, helped preserve manuscripts and promote scholarship on this deliberately compact but consequential oeuvre.

Sound mass

A concentrated musical formation understood primarily through its timbre, register, density, and movement rather than through conventional melody.

Musique concrète

A twentieth-century electronic practice that constructs compositions from recorded and transformed real-world sounds; it developed independently of, but overlapped with, Varèse’s interests.

Spatial music

Music in which the placement and movement of sound sources or loudspeakers form part of the composition.

Electronic tape

Recorded magnetic tape used to preserve, edit, transform, and reproduce electronically generated or recorded sounds.
