Iannis Xenakis was a Greek-French composer, theorist, architect, director, and engineer, born in Romania to Greek parents. He fled Greece in 1947 and became a French citizen in 1965. Xenakis was a pioneer in applying mathematical concepts—such as set theory, stochastic processes, and game theory—to music, and he significantly shaped electronic and computer music. He also merged music with architecture, either composing pieces for existing spaces or designing venues to match specific works and performances.
Key compositions include Metastaseis (1953–54), where each orchestra member plays an independent part; percussion pieces like Psappha (1975) and Pléïades (1979); Terretektorh (1966), which scattered musicians throughout the audience to create spatial effects; electronic works made with his UPIC system; and the large multimedia events he called polytopes. His theoretical book Formalized Music: Thought and Mathematics in Composition (French 1963, English 1971) is considered a major publication. As an architect, Xenakis is best known for collaborating with Le Corbusier on the priory of Sainte-Marie de La Tourette and for independently designing the Philips Pavilion at the 1958 Brussels World’s Fair.
Lore & Background
Giannis Klearchou Xenakis was born in Brăila, Romania, on 29 May 1922, the eldest son of Greek parents. His mother, Fotini Pavlou, a pianist who also spoke German and French, encouraged his early musical interest, giving him a flute and taking the family to the Bayreuth Festival several times. After her death in 1927, when Xenakis was five years old, he was educated by a series of English, French, and German governesses, and then, in 1932, sent to Greece to study at the Anargyrio-Korgialenio boarding school on the Aegean island of Spetses. He excelled in both academics and athletics and sang in the school's boys' choir, where the repertoire included works by Palestrina and Mozart's Requiem, which Xenakis memorized in its entirety.
In 1938, after graduating, he moved to Athens to prepare for entrance exams at its National Technical University, also studying Ancient Greek. He took lessons in harmony and counterpoint with Aristotelis Koundouroff. In 1940, he passed the exams, but his studies were cut short by the Greco-Italian War.
Xenakis joined the National Liberation Front early during the war, participating in mass protests and demonstrations, and later becoming part of armed resistance. After the Axis forces left, the country plunged into a civil war. In December 1944, during Churchill's martial law, Xenakis became involved in street fighting against British tanks.
He was wounded and facially disfigured when shrapnel from a tank blast hit his cheek and left eye, which was blinded. He graduated in 1947 with a degree in civil engineering. Fearing arrest as a left-wing former resistance member, he fled Greece through Italy using a fake passport, arriving in Paris on 11 November 1947. In Greece he was sentenced in absentia to death; the sentence was commuted to ten years' imprisonment in 1951, and only lifted after the fall of the Greek junta in 1974.
Did You Know?
- Olivier Messiaen told Xenakis he was 'so much out of the ordinary' and advised him not to study traditional harmony and counterpoint but to use his background in mathematics and architecture in his music.
Frequently Asked Questions
Who is Iannis Xenakis?
A Romanian-born Greek-French composer, engineer, and architect (1922–2001) who became one of the most radical voices in postwar avant-garde music. He is best known for importing tools from mathematics—stochastic processes, set theory, game theory—directly into the act of composition.
What is Metastaseis?
A string quartet composed in 1953–54 that is often cited as Xenakis's breakthrough work. It uses stochastic (probability-based) processes to determine the distribution of notes, dynamics, and rhythms across the four string parts.
How did Xenakis blend music with architecture?
He created 'polytopes,' immersive spatial compositions in which sound, light, and choreographed movement were mapped onto a specific architectural volume. He also collaborated with Le Corbusier on the Philips Pavilion at the 1958 Brussels World's Fair, where a mathematical surface generated both the structure and the sonic experience.
