Olivier Messiaen

Composer, organist, and ornithologist, one of the major composers of the 20th century.


His music is rhythmically complex; harmonically and melodically it often uses modes of limited transposition, which he abstracted from his early compositions and improvisations. Messiaen also drew on his Roman Catholic faith for his pieces.

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 (a phenomenon known as synaesthesia in its literal manifestation); 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 global musical influences such as Indonesian gamelan (tuned percussion often features prominently in his orchestral works).

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.

His youthful love for the fairy-tale element in Shakespeare prefigured his later expressions of Catholic liturgy. Messiaen was not interested in depicting aspects of theology such as sin; rather he concentrated on the theology of joy, divine love and redemption.
Messiaen continually evolved new composition techniques, always integrating them into his existing musical style; his final works still retain 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.
While he was instrumental in the academic exploration of his techniques (he compiled two treatises: the later one in five volumes was substantially complete when he died and was published posthumously), 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."
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 had a great admiration for the music of Igor Stravinsky, particularly the use of rhythm in earlier works such as The Rite of Spring, and his use of colour. He was further influenced by the orchestral brilliance of Heitor Villa-Lobos, who lived in Paris in the 1920s and gave acclaimed concerts there.
Among composers for the keyboard, Messiaen singled out Jean-Philippe Rameau, Domenico Scarlatti, Frédéric Chopin, Debussy and Isaac Albéniz. He loved the music of Modest Mussorgsky and incorporated varied modifications of what he called the "M-shaped" melodic motif from Mussorgsky's Boris Godunov, although he modified the final interval in this motif from a perfect fourth to a tritone.
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).
Many of Messiaen's composition techniques made use of symmetries of time and pitch.
From his earliest works, Messiaen used non-retrogradable (palindromic) rhythms. 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.

As well as making use of non-retrogradable rhythm and the Hindu decî-tâlas, Messiaen also composed with "additive" rhythms. This involves lengthening individual notes slightly or interpolating a short note into an otherwise regular rhythm, 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's The Rite of Spring, which Messiaen admired.
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 his 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.

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).
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.
