Improvisation can be thought of as an "on the spot" or "[[off the cuff]]" spontaneous moment of sudden inventiveness that can just come to mind, body and spirit as an inspiration. [[Viola Spolin]] created [[theater games]] as a method of training improvisational acting.<ref>{{Cite book|title=Improvisation for the Theater|url=https://archive.org/details/improvisationfor0000spol_v7u4|url-access=registration|last=Spolin|first=Viola|author-link=Viola Spolin|publisher=Northwestern University Press|year=1963|isbn=978-0-8101-4008-0|location=Evanston, Illinois}}</ref> Her son, [[Paul Sills]] popularized improvisational theater, or IMPROV, by using Spolin's techniques to train [[The Second City]] in Chicago, the first totally improvisational theater company in the US.<ref>{{Cite web|title=Viola Spolin|url=https://www.secondcity.com/people/other/viola-spolin/|access-date=2020-11-08|website=The Second City|language=en-US}}</ref>

====Music====
{{main|Musical improvisation}}
[[Musical improvisation]] is usually defined as the spontaneous performance of music without previous preparation or any written notes.<ref>[https://musicterms.artopium.com/i/Improvisation.html Improvisation] musicterms.artopium.com {{Dead link|date=October 2022 |bot=InternetArchiveBot |fix-attempted=yes }}</ref> In other words, the art of improvisation can be understood as composing music "on the fly". There have been experiments by Charles Limb, using [[functional magnetic resonance imaging]], that show the brain activity during musical improvisation.<ref>{{cite web |url=http://www.peabody.jhu.edu/past_issues/fall08/the_science_of_improv.html |title=The Science of Improv |access-date=1 July 2016 |url-status=dead |archive-url=https://web.archive.org/web/20160625073946/http://www.peabody.jhu.edu/past_issues/fall08/the_science_of_improv.html |archive-date=25 June 2016 }}</ref> Limb showed increased activity in the medial prefrontal cortex, which is an area associated with an increase in self-expression. Further, there was decreased activity in the [[lateral prefrontal cortex]], which is an area associated with self-monitoring. This change in activity is thought to reduce the inhibitions that normally prevent individuals from taking risks and improvising.

Notable improvisational musicians from the modern era include [[Keith Jarrett]], an improvisational jazz pianist and multi-instrumentalist who has performed many improvised concerts all over the world;<ref>{{Cite web|date=2016-10-17|title=New Jarrett Box Chronicles Solo Concerts from 1996 Italian Tour|url=https://downbeat.com/news/detail/new-jarrett-box-chronicles-solo-concerts-from-1996-italian-tour|access-date=2020-11-08|website=downbeat.com|language=en}}</ref> [[W.

William Allaudin Mathieu, the musical director for [[The Second City]] in Chicago, the first ongoing improvisational theatre troupe in the United States, and later musical director for another improv theatre, [[The Committee (improv group)|The Committee]], an offshoot of The Second City in San Francisco; [[Derek Bailey (guitarist)|Derek Bailey]], an improvisational guitarist and writer of Improvisation: Its Nature and Practice;<ref>{{Cite book |last=Bailey |first=Derek |title=Improvisation: its nature and practice in music |date=1993 |publisher=Da Capo Press |isbn=978-0-306-80528-8 |location=New York}}</ref> [[Evan Parker]]; British saxophone player, the iconnical pianists [[Fred Van Hove|Fred van Hove]] (Be) and [[Misha Mengelberg]] (NL) and more recently the Belgian [[Seppe Gebruers]] who improvise with two pianos tuned a quartertone apart.<ref>{{Citation |title=Seppe Gebruers |date=2023-10-06 |url=https://en.wikipedia.org/w/index.php?title=Seppe_Gebruers&oldid=1178816683 |work=Wikipedia |access-date=2023-10-11 |language=en}}</ref>

Improvised [[freestyle rap]] is commonly practiced as a part of [[rappers]]' creative processes, as a "finished product" for release on recordings (when the improvisation is judged good enough), as a spiritual event, as a means of verbal combat in [[battle rap]], and, simply, for fun. As mentioned above, studies have suggested that improvisation allows a musician to relax the control filters in their mind during this exercise.<ref>{{Cite web|last=Peak|date=2016-04-27|title=The Neuroscience of Improvisation: Where Genius Rap Lyrics Come From|url=https://medium.com/peak-wellbeing/the-neuroscience-of-improvisation-where-genius-rap-lyrics-come-from-f7717f3230a5|access-date=2020-11-08|website=Medium|language=en}}</ref> It often incorporates insults similar to those in the African-American game [[The Dozens]], and complex rhythmic and sometimes melodic forms comparable to those heard in jazz improvisation.

====Theatre====
{{Main|Improvisational theatre}}
Improvisation, in theatre, is the playing of dramatic scenes without written dialogue and with minimal or no predetermined dramatic activity. The method has been used for different purposes in theatrical history.<ref>{{Cite news|url=https://www.britannica.com/art/improvisation-theatre|title=Improvisation {{!}} theatre|work=Encyclopedia Britannica|access-date=24 October 2018|language=en}}</ref>[[File:Ligue d'improvisation montréalaise (LIM) 20101031-01.jpg|thumb|right|180px|The {{Interlanguage link|Ligue d'improvisation montréalaise|fr}} (LIM) is a league of improvisational theatre based in [[Montreal]], Quebec, Canada]]

====Dance====
[[Dance improvisation]] as a [[choreography|choreographic]] tool: Improvisation is used as a choreographic tool in [[dance composition]]. Experimenting with the concepts of shape, space, time, and energy while moving without inhibition or cognitive thinking can create unique and innovative movement designs, spatial configuration, dynamics, and unpredictable rhythms. Improvisation without inhibition allows the choreographer to connect to their deepest creative self, which in turn clears the way for pure invention. This cognitive inhibition is similar to the inhibition described by Limb for musical improvisation, which can be found in the music section above.

[[Contact improvisation]]: a form developed in 1973, that is now practiced around the world. Contact improvisation originated from the movement studies of Steve Paxton in the 1970s and developed through the continued exploration of the [[Judson Dance Theater]]. It is a dance form based on weight sharing, partnering, playing with weight, exploring negative space and unpredictable outcomes.
