Multitemporal Music
The term polytempo or polytempic is used to describe music in which two or more tempi occur simultaneously. In the Western world, the practice of polytempic music has its roots in the music theory of Henry Cowell, and the early practices of Charles Ives. Later on, composer Elliott Carter, in the fifties, began polymetric experiments in his string quartets that inevitably amounted to polytempic behavior by nature of several competing lines at different surface speeds. At around the same time, composer Henry Brant expanded on Ives's ''The Unanswered Question'' to create a spatial music in which entire ensembles, separated by vast distances, play in distinct simultaneous tempi. Some types of African drumming exhibit this phenomenon. Today's composers are employing polytempi as a compositional strategy to create total and complete independence of line in polyphonic music. Composers such as Conlon Nancarrow, David A. Jaffe, Evgeni Kostitsyn, Kyle Gann, Kenneth Jonsson, John Arrigo-Nels ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Music
Music is generally defined as the art of arranging sound to create some combination of form, harmony, melody, rhythm or otherwise expressive content. Exact definitions of music vary considerably around the world, though it is an aspect of all human societies, a cultural universal. While scholars agree that music is defined by a few specific elements, there is no consensus on their precise definitions. The creation of music is commonly divided into musical composition, musical improvisation, and musical performance, though the topic itself extends into academic disciplines, criticism, philosophy, and psychology. Music may be performed or improvised using a vast range of instruments, including the human voice. In some musical contexts, a performance or composition may be to some extent improvised. For instance, in Hindustani classical music, the performer plays spontaneously while following a partially defined structure and using characteristic motifs. In modal jazz ...

Hemiola
In music, hemiola (also hemiolia) is the ratio 3:2. The equivalent Latin term is sesquialtera. In rhythm, ''hemiola'' refers to three beats of equal value in the time normally occupied by two beats. In pitch, ''hemiola'' refers to the interval of a perfect fifth. Etymology The word ''hemiola'' comes from the Greek adjective ἡμιόλιος, ''hemiolios'', meaning "containing one and a half," "half as much again," "in the ratio of one and a half to one (3:2), as in musical sounds." The words "hemiola" and "sesquialtera" both signify the ratio 3:2, and in music were first used to describe relations of pitch. Dividing the string of a monochord in this ratio produces the interval of a perfect fifth. Beginning in the 15th century, both words were also used to describe rhythmic relationships, specifically the substitution (usually through the use of coloration—red notes in place of black ones, or black in place of "white", hollow noteheads) of three Mensural notation#Proportions a ...

Polymeter
In music, metre ( Commonwealth spelling) or meter (American spelling) refers to regularly recurring patterns and accents such as bars and beats. Unlike rhythm, metric onsets are not necessarily sounded, but are nevertheless implied by the performer (or performers) and expected by the listener. A variety of systems exist throughout the world for organising and playing metrical music, such as the Indian system of '' tala'' and similar systems in Arabic and African music. Western music inherited the concept of metre from poetry, where it denotes: the number of lines in a verse; the number of syllables in each line; and the arrangement of those syllables as long or short, accented or unaccented. The first coherent system of rhythmic notation in modern Western music was based on rhythmic modes derived from the basic types of metrical unit in the quantitative metre of classical ancient Greek and Latin poetry. Later music for dances such as the pavane and galliard consisted of m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polyrhythm
Polyrhythm is the simultaneous use of two or more rhythms that are not readily perceived as deriving from one another, or as simple manifestations of the same meter. The rhythmic layers may be the basis of an entire piece of music (cross-rhythm), or a momentary section. Polyrhythms can be distinguished from irrational rhythms, which can occur within the context of a single part; polyrhythms require at least two rhythms to be played concurrently, one of which is typically an irrational rhythm. Concurrently in this context means within the same rhythmic cycle. The underlying pulse, whether explicit or implicit can be considered one of the concurrent rhythms. For example, the son clave is poly-rhythmic because its 3 section suggests a different meter from the pulse of the entire pattern. In western art music In some European art music, polyrhythm periodically contradicts the prevailing meter. For example, in Mozart's opera ''Don Giovanni'', two orchestras are heard playing toget ...

Postminimalism (music)
Postminimalism is an art term coined (as post-minimalism) by Robert Pincus-Witten in 1971Chilvers, Ian and Glaves-Smith, John, ''A Dictionary of Modern and Contemporary Art'', second edition (Oxford and New York: Oxford University Press, 2009), p. 569. . and used in various artistic fields for work which is influenced by, or attempts to develop and go beyond, the aesthetic of minimalism. The expression is used specifically in relation to music and the visual arts, but can refer to any field using minimalism as a critical reference point. In music, "postminimalism" refers to music following minimal music. Visual art In visual art, postminimalist art uses minimalism either as an aesthetic or conceptual reference point. Postminimalism is more an artistic tendency than a particular movement. Postminimalist artworks are usually everyday objects, use simple materials, and sometimes take on a "pure", formalist aesthetic. However, since postminimalism includes such a diverse and dispar ...

Minimalist Music
In visual arts, Minimal music, music and other media, minimalism is an art movement that began in post–World War II in Western art, most strongly with American visual arts in the 1960s and early 1970s. Prominent artists associated with minimalism include Donald Judd, Agnes Martin, Dan Flavin, Carl Andre, Robert Morris (artist), Robert Morris, Anne Truitt and Frank Stella. The movement is often interpreted as a reaction against abstract expressionism and modernism; it anticipated contemporary Postminimalism, postminimal art practices, which extend or reflect on minimalism's original objectives. Minimal music, Minimalism in music often features repetition and gradual variation, such as the works of La Monte Young, Terry Riley, Steve Reich, Philip Glass, Julius Eastman and John Adams (composer), John Adams. The term ''minimalist'' often colloquially refers to anything or anyone that is spare or stripped to its essentials. It has accordingly been used to describe the Play (theatre) ...

Steve Reich
Stephen Michael Reich ( ; born October 3, 1936) is an American composer known for his contribution to the development of minimal music in the mid to late 1960s. Reich's work is marked by its use of repetitive figures, slow harmonic rhythm, and canons. Reich describes this concept in his essay, "Music as a Gradual Process", by stating, "I am interested in perceptible processes. I want to be able to hear the process happening throughout the sounding music." To do so, his music employs the technique of phase shifting, in which a phrase is slightly altered over time, in a flow that is clearly perceptible to the listener. His innovations include using tape loops to create phasing patterns, as on the early compositions ''It's Gonna Rain'' (1965) and '' Come Out'' (1966), and the use of simple, audible processes, as on ''Pendulum Music'' (1968) and ''Four Organs'' (1970). The 1978 recording ''Music for 18 Musicians'' would help entrench minimalism as a movement. Reich's work took o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phasing (music)
Phase music is a form of music that uses phasing as a primary compositional process. It is an approach to musical composition that is often associated with minimal music, as it shares similar characteristics, but some commentators prefer to treat phase music as a separate category. Phasing is a compositional technique in which the same part (a repetitive phrase) is played on two musical instruments, in steady but not identical tempi. Thus, the two instruments gradually shift out of unison, creating first a slight echo as one instrument plays a little behind the other, then a doubling effect with each note heard twice, then a complex ringing effect, and eventually coming back through doubling and echo into unison. Phasing is the rhythmic equivalent of cycling through the phase of two waveforms as in phasing. Note that the tempi of the two instruments are almost identical, so that both parts are perceived as being in the same tempo: the changes only separate the parts gradually. ...

Iannis Xenakis
Giannis Klearchou Xenakis (also spelled for professional purposes as Yannis or Iannis Xenakis; el, Γιάννης "Ιωάννης" Κλέαρχου Ξενάκης, ; 29 May 1922 – 4 February 2001) was a Romanian-born Greek-French avant-garde composer, music theorist, architect, performance director and engineer. After 1947, he fled Greece, becoming a naturalised citizen of France eighteen years later. Xenakis pioneered the use of mathematical models in music such as applications of set theory, stochastic processes and game theory and was also an important influence on the development of electronic and computer music. He integrated music with architecture, designing music for pre-existing spaces, and designing spaces to be integrated with specific music compositions and performances. Among his most important works are '' Metastaseis'' (1953–54) for orchestra, which introduced independent parts for every musician of the orchestra; percussion works such as '' Psappha'' (197 ...

Studies For Player Piano (Nancarrow)
The ''Studies for Player Piano'' is a series of 49 études for player piano by American composer Conlon Nancarrow. Often exploring complex rhythmic variations beyond the ability of a human pianist, these compositions are some of the best-known and celebrated compositions by Nancarrow, even though they are generally not considered a set of compositions, but rather individual compositions that were given the same title and status. The dates of composition are unknown, but approximate ranges have been given according to best evidence. Composition Nancarrow's ''Studies for Player Piano'' were started when Nancarrow himself was first experimenting with the possibilities of the player piano. Most of these studies were never given a formal premiere and, given that Nancarrow lived his life in relative isolation, his studies became better known after the 80s. Furthermore, most of his studies were arranged for many different ensembles and instruments, including two pianos, small orchestra ...

Player-pianos
A player piano (also known as a pianola) is a self-playing piano containing a pneumatic or electro-mechanical mechanism, that operates the piano action via programmed music recorded on perforated paper or metallic rolls, with more modern implementations using MIDI. The rise of the player piano grew with the rise of the mass-produced piano for the home, in the late 19th and early 20th century. Sales peaked in 1924, then declined, as the improvement in phonograph recordings due to electrical recording methods developed in the mid-1920s. The advent of electrical amplification in home music reproduction via radio in the same period helped cause their eventual decline in popularity, and the stock market crash of 1929 virtually wiped out production. History In 1896, Edwin S. Votey invented the first practical pneumatic piano player, called the Pianola. This mechanism came into widespread use in the 20th century, and was all-pneumatic, with foot-operated bellows providing a sourc ...

György Ligeti
György Sándor Ligeti (; ; 28 May 1923 – 12 June 2006) was a Hungarian-Austrian composer of contemporary classical music. He has been described as "one of the most important avant-garde composers in the latter half of the twentieth century" and "one of the most innovative and influential among progressive figures of his time". Born in Transylvania, Romania, he lived in the Hungarian People's Republic before emigrating to Austria in 1956. He became an Austrian citizen in 1968. In 1973 he became professor of composition at the Hamburg Hochschule für Musik und Theater, where he worked until retiring in 1989. He died in Vienna in 2006. Restricted in his musical style by the authorities of Communist Hungary, only when he reached the West in 1956 could Ligeti fully realise his passion for avant-garde music and develop new compositional techniques. After experimenting with electronic music in Cologne, Germany, his breakthrough came with orchestral works such as ''Atmosphères'', ...
