Editing Free improvisation (section)

== History ==
Though there are many important precedents and developments, free improvisation developed gradually, making it difficult to pinpoint a single moment when the style was born. Free improvisation primarily descends from the [[Indeterminacy (music)|Indeterminacy]] movement and [[free jazz]]. 

Guitarist [[Derek Bailey (guitarist)|Derek Bailey]] contends that free improvisation must have been the earliest musical style, because "mankind's first musical performance couldn't have been anything other than a free improvisation." Similarly, [[Keith Rowe]] stated, "Other players got into playing freely, way before [[AMM (group)|AMM]], way before Derek [Bailey]! Who knows when free playing started? You can imagine [[lute]] players in the 1500s getting drunk and doing improvisations for people in front of a log fire.. the noise, the clatter must have been enormous. You read absolutely incredible descriptions of that. I cannot believe that musicians back then didn't float off into free playing. The [[melisma]] in [[Claudio Monteverdi|Monteverdi]] {{sic}} must derive from that. But it was all in the context of a repertoire."<ref>{{cite web|url=http://www.paristransatlantic.com/magazine/interviews/rowe.html|title=Keith Rowe|last=Warburton|first=Dan|date=January 2001|publisher=Paris Transatlantic Magazine|access-date=2008-04-04}}</ref>

=== Classical precedents ===
By the middle decades of the 20th century, composers such as [[Henry Cowell]], [[Earle Brown]], [[David Tudor]], [[La Monte Young]], [[Jackson Mac Low]], [[Morton Feldman]], [[Sylvano Bussotti]], [[Karlheinz Stockhausen]], and [[George Crumb]], re-introduced improvisation to European art music, with compositions that allowed or even required musicians to improvise. One notable example of this is [[Cornelius Cardew]]'s ''[[Treatise (music)|Treatise]]'': a [[Graphic notation (music)|graphic score]] with no conventional notation whatsoever, which musicians were invited to interpret.

Improvisation is still commonly practised by some organists at concerts or church services, and courses in improvisation (including free improvisation) are part of many higher education programmes for church musicians.<ref>{{cite web|url=http://www.hmtm-hannover.de/en/application/programmes-of-study/church-music-bmus/ |title=HMTM Hannover: Church Music (B.Mus.) |publisher=Hmtm-hannover.de |date=2011-12-30 |access-date=2012-08-03}}</ref>

=== International free improvisation ===
Since 2002 [[New Zealand]] collective Vitamin S has hosted weekly improvisations based around randomly drawn trios.  Vitamin S takes the form beyond music and includes improvisers from other forms such as dance, theatre and puppetry.<ref>{{cite web|url=http://www.95bfm.com/assets/sm/187016/3/insidetrackepi4.mp3|title=Inside Track 2008: Episode 4|publisher=[[95bFM]]|url-status=dead|archive-url=https://web.archive.org/web/20150904063006/http://www.95bfm.com/assets/sm/187016/3/insidetrackepi4.mp3|archive-date=4 September 2015}}</ref>

Since 2006, improvisational music in many forms has been supported and promoted by ISIM, the International Society for Improvised Music. ISIM comprises some 300 performing artists and scholars worldwide, including [[Pauline Oliveros]], [[Robert Dick (flautist)|Robert Dick]], [[Jane Ira Bloom]], [[Roman Stolyar]], [[Mark Dresser]], and many others.

Founded in Manchester, England, in 2007, ''the Noise Upstairs'' has been an institution dedicated to the practice of improvised music,<ref>{{cite web|url=http://www.thenoiseupstairs.com/about/|title=The Noise Upstairs – About|website=thenoiseupstairs.com|access-date=4 April 2018}}</ref> hosting regular concerts and creative workshops where they have promoted international and UK-based artists such as [[Ken Vandermark]],<ref>{{cite web |url=http://www.manchesterscenewipe.co.uk/tag/ken-vandermark-trio/ |title=All things tagged as: Ken Vandermark Trio |access-date=2014-02-10 |url-status=dead |archive-url=https://archive.today/20140214102548/http://www.manchesterscenewipe.co.uk/tag/ken-vandermark-trio/ |archive-date=14 February 2014}}</ref> [[Lê Quan Ninh]], [[Ingrid Laubrock]], and [[Yuri Landman]].  On top of these events, the Noise Upstairs runs monthly jam nights.<ref>{{cite web|url=http://www.thenoiseupstairs.com/category/performances/|title=Performances – The Noise Upstairs|website=thenoiseupstairs.com|access-date=4 April 2018}}</ref>

In Berlin, Germany, from the 1990s onwards, a school of free improvisation emerged known as ''echtzeitmusik'' (‘real-time music’ or ‘immediate music’). This has been sustained by supportive venues such as [[Ausland (Berlin)|ausland]], Anorak Club, Labor Sonor, and others.<ref name=":1">{{Cite journal |title=reSource Chat with Gregor Hotz, ausland |url=https://2020.transmediale.de/sites/default/files/public/imce/nodes/resource/resource_chats/ausland.pdf |journal=ReSource |publisher=transmediale}}</ref>

=== The downtown scene ===
In late 1970s New York a group of musicians came together who shared an interest in free improvisation as well as rock, jazz, contemporary classical, world music and pop. They performed at lofts, apartments, basements and venues located predominantly in [[Lower Manhattan|downtown New York]] ([[8BC]], [[Pyramid Club (New York)|Pyramid Club]], Environ, [[Roulette]], [[The Knitting Factory]] and [[Tonic (music venue)|Tonic]]) and held regular concerts of free improvisation which featured many of the prominent figures in the scene, including [[John Zorn]], [[Bill Laswell]], [[George E. Lewis]], [[Fred Frith]], [[Tom Cora]], [[Toshinori Kondo]], [[Wayne Horvitz]], [[Eugene Chadbourne]], [[Zeena Parkins]], [[Anthony Coleman]], [[Polly Bradfield]], [[Ikue Mori]], [[Robert Dick (flautist)|Robert Dick]], [[Ned Rothenberg]], [[Bob Ostertag]], [[Christian Marclay]], [[David Moss (musician)|David Moss]], [[Kramer (musician)|Kramer]] and many others. They worked with each other, independently and with many of the leading European improvisers of the time, including [[Derek Bailey (guitarist)|Derek Bailey]], [[Evan Parker]], [[Han Bennink]], [[Misha Mengelberg]], [[Peter Brötzmann]] and others. Many of these musicians continue to use improvisation in one form or another in their work.

=== Electronic free improvisation ===
Electronic devices such as oscillators, echoes, filters and alarm clocks were an integral part of free improvisation performances by groups such as [[Kluster]] at the underground scene at Zodiac Club in [[Berlin]] in the late 1960s.<ref>Alan and Steven Freeman: ''The Crack in the Cosmic Egg,'' Audion Publications, 1996, {{ISBN|0-9529506-0-X}}</ref> For the 1975 [[jazz-rock]] concert recording ''[[Agharta (album)|Agharta]]'', [[Miles Davis]] and his band employed free improvisation and electronics,<ref>{{cite news|last=Bayles|first=Martha|author-link=Martha Bayles|date=13 May 2001|title=Miles Davis: The Chameleon of Cool; an Innovator with Dueling Ambitions|newspaper=[[The New York Times]]|page=19}}</ref> particularly guitarist [[Pete Cosey]] who improvised sounds by running his guitar through a [[ring modulator]] and an [[EMS Synthi A]].<ref>{{cite magazine|last=Trzaskowski|first=Andrzej|author-link=Andrzej Trzaskowski|year=1976|issue=40|magazine=[[Jazz Forum (magazine)|Jazz Forum]]|title=Agharta|location=Warsaw|page=74}}</ref>

But it was only later that traditional instruments were disbanded altogether in favour of pure electronic free improvisation. In 1984, the Swiss improvisation duo [[Voice Crack]] started making use of strictly "cracked everyday electronics".<ref>{{cite web|url=http://www.for4ears.com/poire_z/about_poire_z.html |title=about poire_z_fr |publisher=For4ears.com |access-date=2012-08-03 |url-status=dead |archive-url=https://web.archive.org/web/20120716234951/http://www.for4ears.com/poire_z/about_poire_z.html |archive-date=16 July 2012}}</ref>

=== Electroacoustic improvisation ===
{{main|Electroacoustic Improvisation}}
A recent branch of improvised music is characterized by quiet, slow moving, minimalistic textures and often utilizing laptop computers or unorthodox forms of electronics.

Developing worldwide in the mid-to-late 1990s, with centers in New York, Tokyo and Austria, this style has been called ''[[lowercase music]]'' or EAI ([[electroacoustic improvisation]]), and is represented, for instance, by the American record label [[Erstwhile Records]] and the Austrian label [[Mego Records|Mego]].

EAI is often radically different even from established free improvisation. Eyles writes, "One of the problems of describing this music is that it requires a new vocabulary and ways of conveying its sound and impact; such vocabulary does not yet exist – how do you describe the subtle differences between different types of [[audio feedback|controlled feedback]]? I've yet to see anyone do it convincingly – hence the use of words like 'shape' and 'texture'!"<ref>{{cite magazine|url=http://www.allaboutjazz.com/php/article.php?id=22196|title=4g: cloud|last=Eyles|first=John|date=21 June 2006|magazine=All About Jazz|access-date=2008-04-04}}</ref>
