Restricted by the authorities of Communist Hungary, only when he reached the west in 1956 could he fully realise his passion for avant-garde music and develop new compositional techniques. After experimenting with electronic music in Cologne, his breakthrough came with orchestral works such as Atmosphères, for which he used a technique he later dubbed micropolyphony. After writing his "anti-opera" Le Grand Macabre, Ligeti shifted away from chromaticism and towards polyrhythm for his later works.
He is best known by the public for the use of his music in film soundtracks. Although he did not directly compose any film scores, excerpts of pieces composed by him were taken and adapted for film use. Most famously this occurred in the films of Stanley Kubrick, particularly with the music from 2001: A Space Odyssey, which also contained pieces from other classical composers.
Described as "together with Boulez, Berio, Stockhausen, and Cage as one of the most innovative and influential among progressive figures of his time". From about 1960 Ligeti's work became better-known and respected. His best-known work include works in the period from Apparitions (1958–59) to Lontano (1967), which included Atmosphères (1961), Volumina (1961–62, revised 1966), Aventures and Nouvelles Aventures (1962, 1962–65), Requiem (1963–65), Lux Aeterna (1966), Cello Concerto (1966); and his opera Le Grand Macabre (1978). In recent years his three books of Études for piano (1985–2001) have become well known through the Inside the Score project of Pierre-Laurent Aimard.
Ligeti's earlier works used a technique known as micropolyphony. This is a similar technique to polyphony but with the main difference being the polyphony is hidden through a dense and rich stack of pitches.It can be used to create the nearly static but slowly evolving works such as Atmosphères (1961) in which the individual instruments become hidden in a complex polyphony, with only textures apparent. Ligeti says that after this and his earlier piece Apparitions, he became famous.
Ligeti’s music from the last two decades of his life is unmistakable for its rhythmic complexity. Writing about his first book of Piano Etudes, the composer claims this rhythmic complexity stems from two vastly different sources of inspiration: the Romantic-era piano music of Chopin and Schumann and the indigenous music of sub-Saharan Africa.
The difference between the earlier and later pieces lies in a new conception of pulse. In the earlier works, the pulse is something to be divided into two, three and so on. The effect of these different subdivisions, especially when they occur simultaneously, is to blur the aural landscape, creating the micropolyphonic effect of Ligeti’s music.
On the other hand the later music—and a few earlier pieces such as Continuum—conceives of the pulse as a musical atom, a common denominator, a basic unit which cannot be divided any further.
Different rhythms appear through multiplications of the basic pulse, rather than divisions: this is the principle of African music seized on by Ligeti. It also appears in the music of Philip Glass, Steve Reich and others; and significantly it shares much in common with the additive rhythms of Balkan folk music, the music of Ligeti’s youth.
ANALYSYS OF HIS WORKS
Ligeti's earliest works are often an extension of the musical language of Béla Bartók. Even his piano cycle Musica ricercata (1953), though written according to Ligeti with a "Cartesian" approach in which he "regarded all the music I knew and loved as being... irrelevant", has been described by one biographer as inhabiting a world very close to Bartók's set of piano works, Mikrokosmos.
Ligeti's set comprises eleven pieces in all. The work is based on a simple restriction: the first piece uses exclusively one pitch A, heard in multiple octaves, and only at the very end of the piece is a second note, D, heard. The second piece then uses three notes (E♯, F♯, and G), the third piece uses four, and so on, so that in the final piece all twelve notes of the chromatic scale are present. Shortly after its composition Ligeti arranged six of the movements of Musica ricercata for wind quintet under the title 'Six Bagatelles for Wind Quintet'.
The Bagatelles were performed first in 1956, but not in their entirety: the last movement was censored by the Soviets for being too 'dangerous'.
Upon arriving in Cologne he began to write electronic music alongside Karlheinz Stockhausen and Gottfried Michael Koenig at the electronic studio of West German Radio (WDR). He completed only two works in this medium, however—the pieces Glissandi (1957) and Artikulation (1958)—before returning to instrumental music.
A third work, originally entitled Atmosphères but later known as Pièce électronique Nr. 3, was planned, but the technical limitations of the time prevented Ligeti from realizing it completely. It was finally realised in 1996 by the Dutch composers Kees Tazelaar and Johan van Kreij of the Institute of Sonology.
Ligeti's music appears to have been subsequently influenced by his electronic experiments, and many of the sounds he created resembled electronic textures. The texture used in the second movement of Apparitions (1958–59) and Atmosphères (1961) Ligeti would later dub "micropolyphony".
Lux Aeterna (1966) is a 16-voice a cappella piece whose text is also associated with the Latin Requiem.
His Cello Concerto, dedicated to Siegfried Palm (1966) contains two movements. The first movement begins with an almost imperceptible cello which slowly shifts into static tone clusters with the orchestra before reaching a crescendo and slowly decaying. The second movement is a virtuoso piece of dynamic atonal melody on the part of the cello.
In the Chamber Concerto (1969–70), several layers, processes and kinds of movement can take place on different planes simultaneously. In spite of frequent markings of "senza tempo", the instrumentalists are not given linear freedom; Ligeti insists on keeping his texture under strict control at any given moment. The form is like a "precision mechanism".
Ligeti was always fascinated by machines that do not work properly and by the world of technology and automation. The use of periodic mechanical noises, suggesting not-quite-reliable machinery, occurs in many of his works. The scoring is for flute (doubling piccolo), oboe (doubling oboe d'amore and cor anglais), clarinet, bass clarinet (doubling second clarinet), horn, trombone, harpsichord (doubling Hammond organ), piano (doubling celesta), and solo string quartet.
From 1985 to 2001, Ligeti completed three books of Études for piano (Book I, 1985; Book II, 1988–94; Book III, 1995–2001). Comprising eighteen compositions in all, the Études draw from a diverse range of sources, including gamelan, African polyrhythms, Béla Bartók, Conlon Nancarrow, Thelonious Monk, and Bill Evans.
Book I was notably written as preparation for the Piano Concerto, which contains a number of similar motivic and melodic elements.
In 1988, Ligeti completed his Piano Concerto, a work which he described as a statement of his "aesthetic credo". Initial sketches of the Concerto began in 1980, but it was not until 1986 that he found a way forward and the work proceeded more quickly.The Concerto explores many of the ideas worked out in the Études but in an orchestral context.
