Aleatoricism (or aleatorism) is a term for musical compositions and other forms of art[ citation needed ] resulting from "actions made by chance".
The term was first used "in the context of electro-acoustics and information theory" to describe "a course of sound events that is determined in its framework and flexible in detail", by Belgian-German physicist, acoustician, and information theorist Werner Meyer-Eppler. [1] [2] In practical application, in compositions by Mozart and Kirnberger, for instance, the order of the measures of a musical piece were left to be determined by throwing dice, and in performances of music by Pousseur (e.g., Répons pour sept musiciens, 1960), musicians threw dice "for sheets of music and cues". [1] However, more generally in musical contexts, the term has had varying meanings as it was applied by various composers, and so a single, clear definition for aleatory music is defied. [1] The term was popularised by the musical composer Pierre Boulez,[ not verified in body ] but also Witold Lutosławski and Franco Evangelisti.
Its etymology derives from alea, Latin for "dice", [3] and it is the noun associated with the adjectival aleatory and aleatoric.
Aleatory should not be confused with either indeterminacy, [3] or improvisation. [1] [ failed verification ]
Sean Keller and Heinrich Jaeger coined the term aleatory architecture to describe "a new approach that explicitly includes stochastic (re-) configuration of individual structural elements — that is to say 'chance.'" [4]

The term aleatory was first coined by Werner Meyer-Eppler in 1955 to describe a course of sound events that is "determined in general but depends on chance in detail". [2] When his article was published in English, the translator mistakenly rendered his German noun Aleatorik as an adjective, and so inadvertently created a new English word, "aleatoric". [6] Pierre Boulez applied the term "aleatory" in this sense to his own pieces to distinguish them from the indeterminate music of John Cage. [1] While Boulez purposefully composed his pieces to allow the performer certain liberties with regard to the sequencing and repetition of parts, Cage often composed through the application of chance operations without allowing the performer liberties.
Another composer of aleatory music was the German composer Karlheinz Stockhausen, [1] who had attended Meyer-Eppler's seminars in phonetics, acoustics, and information theory at the University of Bonn from 1954 to 1956, [7] and put these ideas into practice for the first time in his electronic composition Gesang der Jünglinge (1955–56), in the form of statistically structured, massed "complexes" of sounds. [8]
Aleatoric techniques are sometimes used in contemporary film music, e.g., in John Williams's film scores[ clarification needed ] and Mark Snow's music for X-Files: Fight the Future. [9]
David Eugene Tudor was an American pianist and composer of experimental music.
John Milton Cage Jr. was an American composer and music theorist. A pioneer of indeterminacy in music, electroacoustic music, and non-standard use of musical instruments, Cage was one of the leading figures of the post-war avant-garde. Critics have lauded him as one of the most influential composers of the 20th century. He was also instrumental in the development of modern dance, mostly through his association with choreographer Merce Cunningham, who was also Cage's romantic partner for most of their lives.
Aleatoricmusic is music in which some element of the composition is left to chance, and/or some primary element of a composed work's realization is left to the determination of its performer(s). The term is most often associated with procedures in which the chance element involves a relatively limited number of possibilities.
20th-century classical music is art music that was written between the years 1901 and 2000, inclusive. Musical style diverged during the 20th century as it never had previously, so this century was without a dominant style. Modernism, impressionism, and post-romanticism can all be traced to the decades before the turn of the 20th century, but can be included because they evolved beyond the musical boundaries of the 19th-century styles that were part of the earlier common practice period. Neoclassicism and expressionism came mostly after 1900. Minimalism started much later in the century and can be seen as a change from the modern to postmodern era, although some date postmodernism from as early as about 1930. Aleatory, atonality, serialism, musique concrète, and electronic music were all developed during the century. Jazz and ethnic folk music became important influences on many composers during this century.
Gesang der Jünglinge is an electronic music work by Karlheinz Stockhausen. It was realized in 1955–56 at the Westdeutscher Rundfunk studio in Cologne and is Work Number 8 in the composer's catalog. The vocal parts were supplied by 12-year-old Josef Protschka. It is exactly 13 minutes, 14 seconds long.
Witold Roman Lutosławski was a Polish composer and conductor. Among the major composers of 20th-century classical music, he is "generally regarded as the most significant Polish composer since Szymanowski, and possibly the greatest Polish composer since Chopin". His compositions—of which he was a notable conductor—include representatives of most traditional genres, aside from opera: symphonies, concertos, orchestral song cycles, other orchestral works, and chamber works. Among his best known works are his four symphonies, the Variations on a Theme by Paganini (1941), the Concerto for Orchestra (1954), and his cello concerto (1970).
Electroacoustic music is a genre of popular and Western art music in which composers use technology to manipulate the timbres of acoustic sounds, sometimes by using audio signal processing, such as reverb or harmonizing, on acoustical instruments. It originated around the middle of the 20th century, following the incorporation of electric sound production into compositional practice. The initial developments in electroacoustic music composition to fixed media during the 20th century are associated with the activities of the Groupe de recherches musicales at the ORTF in Paris, the home of musique concrète, the Studio for Electronic Music in Cologne, where the focus was on the composition of elektronische Musik, and the Columbia-Princeton Electronic Music Center in New York City, where tape music, electronic music, and computer music were all explored. Practical electronic music instruments began to appear in the early 20th century.
In music, modernism is an aesthetic stance underlying the period of change and development in musical language that occurred around the turn of the 20th century, a period of diverse reactions in challenging and reinterpreting older categories of music, innovations that led to new ways of organizing and approaching harmonic, melodic, sonic, and rhythmic aspects of music, and changes in aesthetic worldviews in close relation to the larger identifiable period of modernism in the arts of the time. The operative word most associated with it is "innovation". Its leading feature is a "linguistic plurality", which is to say that no one music genre ever assumed a dominant position.
Inherent within musical modernism is the conviction that music is not a static phenomenon defined by timeless truths and classical principles, but rather something which is intrinsically historical and developmental. While belief in musical progress or in the principle of innovation is not new or unique to modernism, such values are particularly important within modernist aesthetic stances.
Franco Evangelisti was an Italian composer specifically interested in the scientific theories behind sound.
Darmstadt School refers to a group of composers who were associated with the Darmstadt International Summer Courses for New Music from the early 1950s to the early 1960s in Darmstadt, Germany, and who shared some aesthetic attitudes. Initially, this included only Pierre Boulez, Bruno Maderna, Luigi Nono, and Karlheinz Stockhausen, but others came to be added, in various ways. The term does not refer to an educational institution.
Werner Meyer-Eppler, was a Belgian-born German physicist, experimental acoustician, phoneticist and information theorist.
Herbert Eimert was a German music theorist, musicologist, journalist, music critic, editor, radio producer, and composer.
Die Reihe was a German-language music academic journal, edited by Herbert Eimert and Karlheinz Stockhausen and published by Universal Edition (Vienna) between 1955 and 1962. An English edition was published, under the original German title, between 1957 and 1968 by the Theodore Presser Company in association with Universal Edition (London). A related book series titled "Bücher der Reihe" was begun, but only one title ever appeared in it, Herbert Eimert's Grundlagen der musikalischen Reihentechnik.
Hans G Helms was a German experimental writer, composer, and social and economic analyst and critic.
Indeterminacy is a composing approach in which some aspects of a musical work are left open to chance or to the interpreter's free choice. John Cage, a pioneer of indeterminacy, defined it as "the ability of a piece to be performed in substantially different ways".
Experimental music is a general label for any music or music genre that pushes existing boundaries and genre definitions. Experimental compositional practice is defined broadly by exploratory sensibilities radically opposed to, and questioning of, institutionalized compositional, performing, and aesthetic conventions in music. Elements of experimental music include indeterminacy, in which the composer introduces the elements of chance or unpredictability with regard to either the composition or its performance. Artists may approach a hybrid of disparate styles or incorporate unorthodox and unique elements.
Zeitmaße is a chamber-music work for five woodwinds composed in 1955–1956 by German composer Karlheinz Stockhausen; it is Number 5 in the composer's catalog. It is the first of three wind quintets written by Stockhausen, followed by Adieu für Wolfgang Sebastian Meyer (1966) and the Rotary Wind Quintet (1997), but is scored with cor anglais instead of the usual French horn of the standard quintet. Its title refers to the different ways that musical time is treated in the composition.
The Studio for Electronic Music of the West German Radio was a facility of the Westdeutscher Rundfunk (WDR) in Cologne. It was the first of its kind in the world, and its history reflects the development of electronic music in the second half of the twentieth century.
Jeux vénitiens is a 1961 composition by Polish composer Witold Lutosławski, under commission from the Krakow Philharmonic. It premiered April 24, 1961 in Venice. Another performance occurred at Warsaw Autumn in 1961.
Lousadzak, Op. 48, is a 1944 concerto for piano and string orchestra by the American-Armenian composer Alan Hovhaness. Duration of the piece is about 18 minutes. The work is known for its use of aleatory that is said to have impressed fellow composers Lou Harrison and John Cage, and anticipated "many soon-to-be-hip" aleatory techniques.
The concept of 'aleatory' was preferred by European composers, among them Pierre Boulez, Witold Lutosławski and Franco Evangelisti. It was first used by Werner Meyer-Eppler in the context of electro-acoustics and information theory for describing a course of sound events that is determined in its framework and flexible in detail.(6) Aleatory, a word derived from the Latin alea, has many different meanings such as dice, game of dice, risk, danger, bad surprise, and chance. Most composers using aleatory referred to the meaning of chance, but some composers referred to meanings like risk (for instance Evangelisti) and dice (Henri Pousseur composed a piece called Répons pour sept musiciens, 1960, where performers throw dice for sheets of music and cues, a procedure similar to pieces by Kirnberger or Mozart in which the order of the measures is determined by throwing a dice.). Many composers thought they dealt with chance and created chance compositions when they allowed for greater performance flexibility. None of them used chance operations as Cage did. Since many composers were skeptical about "pure" chance and mere accident they came up with the idea of "controlled chance" and "limited aleatorism" (preferred by Lutosławski).
The term aleatory was popularized in Europe by Pierre Boulez means a musical result of actions made by chance ("alea" is Latin for "dice") or choice. The composers offered the players, for example, choices of route through the fragments of their work, allowed them to join these elements freely but, at the same time, they were completely responsible for the overall shape of the work. Aleatory music is sometimes treated as a synonym of indeterminate music (indeterminacy) but the latter term was preferred by John Cage and meant not only performance liberties but also the use of chance element in the process of composition. Although aleatoricism is an extremely different musical concept than serialism, the end result of both ideas may sound surprisingly alike.
