He travelled widely and wrote works inspired by diverse influences such as Japanese music, the landscape of Bryce Canyon in Utah and the life of St. Francis of Assisi. He said he perceived colours when he heard certain musical chords, particularly those built from his modes (a phenomenon known as synaesthesia); combinations of these colours, he said, were important in his compositional process. For a short period Messiaen experimented with the parametrisation associated with "total serialism", in which field he is often cited as an innovator. His style absorbed many exotic musical influences such as Indonesian gamelan (tuned percussion often features prominently in his orchestral works). He was one of the first composers to use an electronic keyboard—in this case, the ondes Martenot—in an orchestral work.
He found birdsong fascinating, believed birds to be the greatest musicians, and considered himself as much an ornithologist as a composer. He notated bird songs worldwide and incorporated birdsong transcriptions into most of his music. His innovative use of colour, his conception of the relationship between time and music, his use of birdsong and his desire to express religious ideas are among features that make Messiaen's music distinctive.
Olivier Eugène Prosper Charles Messiaen was born in Avignon, France into a literary family. He was the elder of two sons of Cécile Sauvage, a poet, and Pierre Messiaen, a teacher of English who translated the plays of William Shakespeare into French. Messiaen's mother published a sequence of poems, L'âme en bourgeon ("The Budding Soul"), the last chapter of Tandis que la terre tourne ("As the Earth Turns"), which address her unborn son. Messiaen later said this sequence of poems influenced him deeply and he cited it as prophetic of his future artistic career.
At the outbreak of World War I, Pierre Messiaen enlisted and Cécile took their two boys to live with her brother in Grenoble. There Messiaen became fascinated with drama, reciting Shakespeare to his brother with the help of a home-made toy theatre with translucent backdrops made from old cellophane wrappers. At this time he also adopted the Roman Catholic faith. Later, Messiaen felt most at home in the Alps of the Dauphiné, where he had a house built south of Grenoble where he composed most of his music.
He took piano lessons having already taught himself to play. His interest included the recent music of French composers Claude Debussy and Maurice Ravel, and he asked for opera vocal scores for Christmas presents. Around this time he began to compose. In 1918 his father returned from the war and the family moved to Nantes. He continued music lessons; one of his teachers, Jehan de Gibon, gave him a score of Debussy's opera Pelléas et Mélisande, which Messiaen described as "a thunderbolt" and "probably the most decisive influence on me". The following year Pierre Messiaen gained a teaching post in Paris. Messiaen entered the Paris Conservatoire in 1919, aged 11.
At the Conservatoire, Messiaen made excellent academic progress, topping the class many times. In 1924, aged 15, he was awarded second prize in harmony; having been taught in that subject by professor Jean Gallon. In 1926, he gained first prize in counterpoint and fugue, and in 1927 he won first prize in piano accompaniment. After studying with Maurice Emmanuel, he was awarded first prize for the history of music in 1928. Emmanuel's example engendered an interest in ancient Greek rhythms and exotic modes. After showing improvisation skills on the piano Messiaen studied organ with Marcel Dupré and inherited the tradition of great French organists (Dupré had studied with Charles-Marie Widor and Louis Vierne, Vierne in turn was a pupil of César Franck). Messiaen gained first prize in organ playing and improvisation in 1929. After a year studying composition with Charles-Marie Widor, in the autumn of 1927 he entered the class of the newly appointed Paul Dukas, who instilled in Messiaen a mastery of orchestration. In 1930 Messiaen won first prize in composition.
While a student he composed his first published works—his eight Préludes for piano (the earlier Le banquet céleste was published subsequently). These exhibit Messiaen's use of his modes of limited transposition and palindromic rhythms (Messiaen called these non-retrogradable rhythms). His public début came in 1931 with his orchestral suite Les offrandes oubliées. That year he first heard a gamelan group, sparking his interest in the use of tuned percussion.
In the autumn of 1927, Messiaen joined Dupré's organ course. Dupré later wrote that Messiaen, having never seen an organ console, sat quietly for an hour while Dupré explained and demonstrated the instrument, and then came back a week later to play Johann Sebastian Bach's Fantasia in C minor to an impressive standard. From 1929, Messiaen regularly deputised at the Église de la Sainte-Trinité, Paris for the organist Charles Quef, who was ill at the time. The post became vacant in 1931 when Quef died, and Dupré, Charles Tournemire and Widor among others supported Messiaen's candidacy. His formal application included a letter of recommendation from Widor. The appointment was confirmed in 1931, and he remained the organist at la Sainte-Trinité for more than sixty years.
He married the violinist and composer Claire Delbos in 1932. Their marriage inspired him to both compose works for her to play (Thème et variations for violin and piano in the year they were married) and to write pieces to celebrate their domestic happiness, including the song cyclePoèmes pour Mi in 1936, which he orchestrated in 1937. Mi was Messiaen's affectionate nickname for his wife. In 1937 their son Pascal was born. The marriage turned to tragedy when Delbos lost her memory after an operation and spent the rest of her life in mental institutions.
In 1936, along with André Jolivet, Daniel-Lesur and Yves Baudrier, Messiaen formed the group La jeune France ("Young France"). Their manifesto implicitly attacked the frivolity predominant in contemporary Parisian music and rejected Jean Cocteau's 1918 Le coq et l'arlequin manifesto in favour of a "living music, having the impetus of sincerity, generosity and artistic conscientiousness". Messiaen's career soon departed from this polemical phase.
In response to a commission for a piece to accompany light-and water-shows on the Seine during the Paris Exposition, in 1937 Messiaen demonstrated his interest in using the ondes Martenot, an electronic instrument, by composing Fêtes des belles eaux for an ensemble of six. He included a part for the instrument in several of his subsequent compositions. During this period he composed several multi-movement organ works. He arranged his orchestral suite L'ascension ("The Ascension") for organ, replacing the orchestral version's third movement with an entirely new movement, Transports de joie d'une âme devant la gloire du Christ qui est la sienne ("Ecstasies of a soul before the glory of Christ, which is its own glory"). (listen (help·info)) This movement became one of Messiaen's most popular pieces. He also wrote the extensive cycles La nativité du seigneur ("The Nativity of the Lord") and Les corps glorieux ("The glorious bodies"). The final toccata of La nativité, Dieu parmi nous ("God among us"), has become another favourite recital piece.
At the outbreak of World War II, Messiaen was drafted into the French army. Due to poor eyesight, he was enlisted as a medical auxiliary rather than an active combatant. He was captured at Verdun and taken to Görlitz in May 1940, and was imprisoned at Stalag VIII-A. He met a violinist, a cellist and a clarinettist among his fellow prisoners. He wrote a trio for them, which he gradually incorporated into his Quatuor pour la fin du temps ("Quartet for the End of Time"). The quartet was first performed in January 1941 to an audience of prisoners and prison guards, with the composer playing a poorly maintained upright piano in freezing conditions. Thus the enforced introspection and reflection of camp life bore fruit in one of 20th-century European classical music's acknowledged masterpieces. The title's "end of time" alludes to the Apocalypse, and also to the way in which Messiaen, through rhythm and harmony, used time in a manner completely different from his predecessors and contemporaries.
Shortly after his release from Görlitz in May 1941, Messiaen was appointed a professor of harmony at the Paris Conservatoire, where he taught until his retirement in 1978. He compiled his Technique de mon langage musical ("Technique of my musical language") published in 1944, in which he quotes many examples from his music, particularly the Quartet. Although only in his mid-thirties, his students described him as an outstanding teacher, who, rather than imposing his own ideas, encouraged his pupils to find their own voice. Among his early students were the composers Pierre Boulez and Karel Goeyvaerts and the pianist Yvonne Loriod. Other pupils included Karlheinz Stockhausen in 1952, Alexander Goehr in 1956–57, György Kurtág in 1957, Tristan Murail in 1967–72 and George Benjamin during the late 1970s. The Greek composer Iannis Xenakis was referred to him in 1951; Messiaen urged Xenakis to take advantage of his background in mathematics and architecture in his music.
In 1943, Messiaen wrote Visions de l'Amen ("Visions of the Amen") for two pianos for Loriod and himself to perform. Shortly thereafter he composed the enormous solo piano cycle Vingt regards sur l'enfant-Jésus ("Twenty gazes on the child Jesus") for her. Again for Loriod, he wrote Trois petites liturgies de la présence divine ("Three small liturgies of the Divine Presence") for female chorus and orchestra which includes a difficult solo piano part. In this way, Messiaen continued to bring liturgical subjects to the piano recital and concert hall.
Two years after Visions de l'Amen,, Messiaen composed the song cycle Harawi, the first of three works inspired by the legend of Tristan and Isolde. The second of these works about human (as opposed to divine) love was the result of a commission from Serge Koussevitsky (Messiaen stated that the commission did not specify the length of the work or the size of the orchestra); this was the ten-movement Turangalîla-Symphonie. It was not a conventional symphony, but rather an extended meditation on the joy of human union and love. It does not contain the sexual guilt inherent in Richard Wagner's Tristan und Isolde because Messiaen believed that sexual love is a divine gift. (listen (help·info)) The third piece inspired by the Tristan myth was Cinq rechants for twelve unaccompanied singers, described by Messiaen as influenced by the alba of the troubadours. Messiaen visited the United States in 1947, where his music was conducted by Koussevitsky and Leopold Stokowski. His Turangalîla-Symphonie was first performed in America in 1949, conducted by Leonard Bernstein.
Messiaen taught an analysis class at the Paris Conservatoire, and in 1947 he taught in Budapest and in 1949 at Tanglewood. During the summers of 1949 and 1950 he taught in the new music summer school classes at Darmstadt. While he did not employ the twelve-tone technique, after three years teaching analysis of twelve-tone scores, including works by Arnold Schoenberg, he experimented with ways of making scales of other elements (including duration, articulation and dynamics) analogous to the chromatic pitch scale. The results of these innovations was the "Mode de valeurs et d'intensités" for piano (from the Quatre études de rhythme) which has been misleadingly described as the first work of total serialism, though it had a large influence on the earliest European serial composers including Pierre Boulez, Karel Goeyvaerts, and Karlheinz Stockhausen. During this period he also experimented with musique concrète, music for recorded sounds.
Birdsong and the 1960s
When in 1952 Messiaen was asked to provide a test piece for flautists wishing to enter the Paris Conservatoire, he composed the piece Le merle noir for flute and piano. While he had long been fascinated by birdsong, and birds had made appearances in several of his earlier works (for example La nativité, Quatuor and Vingt regards), the flute piece was based entirely on the song of the blackbird.
He took this development to a new level with his 1953 orchestral work Réveil des oiseaux—its material consists almost entirely of the birdsong one might hear between midnight and noon in the Jura. From this period onwards, Messiaen incorporated birdsong into all of his compositions and composed several works for which birds provide both the title and subject matter (for example the collection of thirteen pieces for piano Catalogue d'oiseaux completed in 1958, and La fauvette des jardins of 1971). Far from being simple transcriptions of birdsong, these works are sophisticated tone poems evoking both place and atmosphere. Paul Griffiths observed that Messiaen was a more conscientious ornithologist than any previous composer, and a more musical observer of birdsong than any previous ornithologist.
The Garden Warbler provided the title and much of the material for Messiaen's La fauvette des jardins.
Messiaen's first wife died in 1959 after a long illness, and in 1961 he married pianist Yvonne Loriod. He began to travel widely, to attend musical events and to seek out and transcribe the songs of more exotic birds in the wild. Loriod frequently assisted her husband's detailed studies of birdsong while walking with him, by making tape recordings for later reference. In 1962 he visited Japan, where Gagaku music and Noh theatre inspired the orchestral "Japanese sketches", Sept haïkaï, which contain stylised imitations of traditional Japanese instruments.
Messiaen's music was by this time championed by, among others, Pierre Boulez, who programmed first performances at his Domaine musical concerts and the Donaueschingen festival. Works performed included Réveil des oiseaux, Chronochromie (commissioned for the 1960 festival) and Couleurs de la cité céleste. The latter piece was the result of a commission for a composition for three trombones and three xylophones; Messiaen added to this more brass, wind, percussion and piano, and specified a xylophone, xylorimba and marimba rather than three xylophones. Another work of this period, Et exspecto resurrectionem mortuorem, was commissioned as a commemoration of the dead of the two World Wars and was performed first semi-privately in the Sainte-Chapelle, then publicly in Chartres Cathedral with Charles de Gaulle in the audience.
Transfiguration, Canyons, St. Francis, and the Beyond
Messiaen's next work was the enormous La transfiguration de notre seigneur Jésus-Christ. The composition occupied him from 1965 to 1969 and the musicians employed include a 100-voice ten-part choir, seven solo instruments and large orchestra. Its fourteen movements are a meditation on the story of Christ's Transfiguration. Shortly after its completion, Messiaen received a commission from Alice Tully for a work to celebrate the U.S. bicentennial. He arranged a visit to the USA in spring 1972, and was inspired by Bryce Canyon in Utah, where he observed the canyon's distinctive colours and birdsong. The twelve-movement orchestral piece Des canyons aux étoiles… was the result, which was first performed in 1974 in New York.
In 1971, he was asked to compose a piece for the Paris Opéra. While reluctant to undertake such a major project, he was persuaded in 1975 to accept the commission and began work on his Saint-François d'Assise. The composition was intensive (he also wrote his own libretto) and occupied him from 1975–79; the orchestration was carried out from 1979 until 1983. Messiaen preferred to describe the final work as a "spectacle" rather than an opera. It was first performed in 1983. Some commentators at the time thought that the opera would be his valediction (at times Messiaen himself believed so), but he continued to compose. In 1984 he published a major collection of organ pieces, Livre du Saint Sacrement; other works include birdsong pieces for solo piano, and works for piano with orchestra.
In the summer of 1978, Messiaen retired from teaching at the Conservatoire. He was promoted to the highest rank of the Légion d'honneur, the Grand-Croix, in 1987. An operation prevented his participation in the celebration of his 70th birthday in 1978, but in 1988 tributes for Messiaen's 80th included a complete performance in London's Royal Festival Hall of St. François, which the composer attended, and Erato's publication of a seventeen-CD collection of Messiaen's music including recordings by Loriod and a disc of the composer in conversation with Claude Samuel.
Although in considerable pain near the end of his life (requiring repeated surgery on his back) he was able to fulfil a commission from the New York Philharmonic Orchestra, Éclairs sur l'au-delà…, which was premièred six months after his death. On going through his papers, Messiaen's widow discovered that he had been composing a concerto for four musicians he felt particularly grateful to, namely Loriod, the cellistMstislav Rostropovich, the oboistHeinz Holliger and the flautist Catherine Cantin (hence the title Concert à quatre). This was substantially complete; Yvonne Loriod undertook the final movement's orchestration with advice from George Benjamin.
Messiaen's music has been described as outside the western musical tradition, although growing out of that tradition and being influenced by it. Much of his output denies the western conventions of forward motion, development and diatonic harmonic resolution. This is partly due to the symmetries of his technique—for instance the modes of limited transposition do not admit the conventional cadences found in western classical music.
Example 1. A page from Oiseaux exotiques. It illustrates Messiaen's use of ancient and exotic rhythms (in the percussion near the bottom of the score "Asclepiad" and "Sapphic" are ancient Greek rhythms, and Nibçankalîla is a decî-tâla from Śārṅgadeva). It also illustrates Messiaen's precision in notating birdsong: the birds identified here are the white-crested laughing thrush (garralaxe à huppe blanche) in the brass and wind instruments, and the orchard oriole (troupiale des vergers) played on the xylophone.
Although Messiaen continually evolved new composition techniques, he integrated them into his musical style; his final work still retains the use of modes of limited transposition. For many commentators this continual development made every major work from the Quatuor onwards a conscious summation of all that Messiaen had composed up to that time. However, very few of these major works lack new technical ideas—simple examples being the introduction of communicable language in Meditations, the invention of a new percussion instrument (the geophone) for Des canyons aux etoiles..., and the freedom from any synchronisation with the main pulse of individual parts in certain birdsong episodes of St. François d'Assise.
As well as discovering new techniques, Messiaen found and absorbed exotic music, including Ancient Greek rhythms, Hindu rhythms (he encountered Śārṅgadeva's list of 120 rhythmic units, the deçî-tâlas), Balinese and Javanese Gamelan, birdsong and Japanese music (see Example 1 for an instance of his use of ancient Greek and Hindu rhythms).
While he was instrumental in the academic exploration of his techniques (he published two treatises, the later one in five volumes which was substantially complete when he died), and was himself a master of music analysis, he considered the development and study of techniques to be a means to intellectual, aesthetic and emotional ends. Thus Messiaen maintained that a musical composition must be measured against three separate criteria: it must be interesting, beautiful to listen to, and it must touch the listener.
Messiaen wrote a large body of music for the piano. Although a considerable pianist himself, he was undoubtedly assisted by Yvonne Loriod's formidable piano technique and ability to convey complex rhythms and rhythmic combinations; in his piano writing from Visions de l'Amen onwards he had her in mind. Messiaen said, "I am able to allow myself the greatest eccentricities because to her anything is possible."
Western artistic influences
Developments in modern French music were a major influence on Messiaen, particularly the music of Claude Debussy and his use of the whole-tone scale (which Messiaen called Mode 1 in his modes of limited transposition). Messiaen very rarely used the whole-tone scale in his compositions because, he said, after Debussy and Dukas there was "nothing to add", but the modes he did use are all similarly symmetrical.
Messiaen was further influenced by Surrealism, as may be seen from the titles of some of the piano Préludes (Un reflet dans le vent…, "A reflection in the wind") and in some of the imagery of his poetry (he published poems as prefaces to certain works, for example Les offrandes oubliées).
In certain of Messiaen's scores, he notated the colours in the music (notably in Couleurs de la cité céleste and Des canyons aux étoiles...)— the purpose being to aid the conductor in interpretation rather than to specify which colours the listener should experience. The importance of colour is linked to Messiaen's synaesthesia, which he said caused him to experience colours when he heard or imagined music (he said that he did not perceive the colours visually). In his multi-volume music theory treatise Traité de rythme, de couleur, et d'ornithologie ("Treatise of Rhythm, Colour and Birdsong"), Messiaen wrote descriptions of the colours of certain chords. His descriptions ranging from the simple ("gold and brown") to the highly detailed ("blue-violet rocks, speckled with little grey cubes, cobalt blue, deep Prussian blue, highlighted by a bit of violet-purple, gold, red, ruby, and stars of mauve, black and white. Blue-violet is dominant").
When asked what Messiaen's main influence had been on composers, George Benjamin said, "I think the sheer [...] colour has been so influential, [...] rather than being a decorative element, [Messiaen showed that colour] could be a structural, a fundamental element, [...] the fundamental material of the music itself."
Many of Messiaen's composition techniques made use of symmetries of time and pitch.
Example 2. The first bar of the piano Prélude, Instants défunts. An early example of Messiaen's use of palindromic rhythms (which he called non-retrogradable rhythms).
From his earliest works, Messiaen used non-retrogradable (palindromic) rhythms (Example 2). He sometimes combined rhythms with harmonic sequences in such a way that if the process were allowed to proceed indefinitely the music would eventually run through all the possible permutations and return to its starting point. For Messiaen, this represented the "charm of impossibilities" of these processes. He only ever presented a portion of any such process, as if allowing the informed listener a glimpse of something eternal. In the first movement of Quatuor pour la fin du temps the piano and cello together provide an early example.
Messiaen used modes which he called modes of limited transposition. They are distinguished as groups of notes which can only be transposed by a semitone a limited number of times. For example the whole-tone scale (Messiaen's Mode 1) only exists in two transpositions: namely C–D–E–F♯–G♯–A♯ and D♭–E♭–F–G–A–B. Messiaen abstracted these modes from the harmony of his improvisations and early works. Music written using the modes avoids conventional diatonic harmonic progressions, since for example Messiaen's Mode 2 (identical to the octatonic scale used also by other composers) permits precisely the dominant seventh chords whose tonic the mode does not contain. For Messiaen the modes possessed colours.
Time and rhythm
Example 3. An excerpt from Danse de la fureur, pour les sept trompettes from the Quatuor pour la fin du temps. It illustrates Messiaen's use of additive rhythms - in this example the addition of unpaired semiquavers (sixteenth notes) to an underlying quaver (eighth note) pulse and the lengthening of the final quaver by addition of a dot. It illustrates the use of what Messiaen called the Boris M-shaped motif (the last five notes of the excerpt).
Messiaen considered his rhythmic contribution to music to be his distinguishing mark among modern composers. As well as making use of non-retrogradable rhythms, and the Hindu decî-tâlas, Messiaen also made use of "additive" rhythms. This involves lengthening individual notes slightly or interpolating a short note into an otherwise regular rhythm (see Example 3 or listen (help·info) to Danse de fureur from the Quatuor), or shortening or lengthening every note of a rhythm by the same duration (adding a semiquaver to every note in a rhythm on its repeat, for example). This led Messiaen to use rhythmic cells that irregularly alternate between two and three units, a process which also occurs in Stravinsky'sThe Rite of Spring which Messiaen admired.
A factor that contributes to Messiaen's suspension of the conventional perception of time in his music is the extremely slow tempos he often specifies (the fifth movement Louange à l'eternité de Jésus of Quatuor is actually given the tempo marking infiniment lent); and even in his quick music he often uses repeated phrases and harmonies to make the speed seem static.
Messiaen also used the concept of "chromatic durations", for example in his Soixante-quatre durées from Livre d'orgue, (listen (help·info)) which is built from, in Messiaen's words, "64 chromatic durations from 1 to 64 demisemiquavers [thirty-second notes] - invested in groups of 4, from the ends to the centre, forwards and backwards alternately - treated as a retrograde canon. The whole peopled with birdsong."
Example 4. The song of the golden oriole from Le loriot, part of Catalogue d'oiseaux. The birdsong played by the pianist's left hand (notated on the lower staff) provides the fundamental notes, and the quieter harmonies played by the right hand (on the upper staff) alter their timbre.
In addition to making harmonic use of the modes of limited transposition, he cited the harmonic series as a physical phenomenon which provides chords with a context which he felt to be missing in purely serial music. An example of Messiaen's harmonic use of this phenomenon, which he called "resonance", is the last two bars of Messiaen's first piano Prélude, La colombe ("The dove"); the chord is built from harmonics of the fundamental base note E.
Related to this use of resonance, Messiaen also composed music in which the lowest, or fundamental, note is combined with higher notes or chords played much more quietly. These higher notes, far from being perceived as conventional harmony, function as harmonics that alter the timbre of the fundamental note like mixture stops on a pipe organ. An example is the song of the golden oriole in Le loriot of the Catalogue d'oiseaux for solo piano (Example 4).
In his use of conventional diatonic chords, Messiaen often transcended their historically banal connotations (for example, his frequent use of the added sixth chord as a resolution).
Birdsong fascinated Messiaen from an early age, and in this he found encouragement from his teacher Dukas who reportedly urged his pupils to "listen to the birds". Messiaen included stylised birdsong in some of his early compositions (including L'abîme d'oiseaux from the Quatuor pour la fin du temps), integrating it into his sound-world by techniques like the modes of limited transposition and chord colouration. His evocations of birdsong became increasingly sophisticated, and with Le réveil des oiseaux this process reached maturity, the whole piece being built from birdsong: in effect it is a dawn chorus for orchestra. The same can be said for "Epode", the five-minute sixth movement of "Chronochromie", which is scored for eighteen violins, each one playing a different birdsong. Messiaen notated the bird species with the music in the score (Examples 1 and 4). The pieces are not simple transcriptions; even the works with purely bird-inspired titles, such as Catalogue d'oiseaux and Fauvette des jardins, are tone poems evoking the landscape, its colours and atmosphere. (listen (help·info))
For some compositions, Messiaen created scales for duration, attack and timbre analogous to the chromatic pitch scale. He expressed annoyance at the historical importance given to one of these works, Mode de valeurs et d'intensités, by musicologists intent on crediting him with the invention of "total serialism".
Messiaen later introduced what he called a "communicable language", a "musical alphabet" to encode sentences. He first used this technique in his Méditations sur le mystère de la Sainte Trinité for organ; where the "alphabet" includes motifs for the concepts to have, to be and God, while the sentences encoded feature sections from the writings of St. Thomas Aquinas.
