Viola Spolin created
theater games as a method of training improvisational acting. 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.
Music Musical improvisation is usually defined as the spontaneous performance of music without previous preparation or any written notes. 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. 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;
W. A. Mathieu a.k.a. 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, an offshoot of The Second City in San Francisco;
Derek Bailey, an improvisational guitarist and writer of Improvisation: Its Nature and Practice;
Evan Parker; British saxophone player, the iconnical pianists
Fred van Hove (Be) and
Misha Mengelberg (NL) and more recently the Belgian
Seppe Gebruers who improvise with two pianos tuned a quartertone apart. 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. 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 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., Quebec, Canada
Dance Dance improvisation as a
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.
Sculpture Sculpture often relies on the enlargement of a small model or
maquette to create the final work in a chosen material. Where the material is
plastic such as
clay, a working structure or
armature often needs to be built to allow the pre-determined design to be realized.
Alan Thornhill's method for working with clay abandons the maquette, seeing it as
ultimately deadening to creativity. Without the restrictions of the armature, a clay matrix of elements allows that when recognizable forms start to emerge, they can be essentially disregarded by turning the work, allowing for infinite possibility and the chance for the unforeseen to emerge more powerfully at a later stage. Moving from
adding and taking away to purely reductive working, the architectural considerations of turning the work are eased considerably but continued removal of material through the rejection of forms deemed
too obvious can mean one ends up with nothing. Former pupil
Jon Edgar uses Thornhill's method as a creative extension to
direct carving in stone and wood.
Film The director
Mike Leigh uses lengthy improvisations developed over a period of weeks to build characters and story lines for his films. He starts with some sketch ideas of how he thinks things might develop but does not reveal all his intentions with the cast who discover their fate and act out their responses as their destinies are gradually revealed, including significant aspects of their lives which will not subsequently be shown onscreen. The final filming draws on dialogue and actions that have been recorded during the improvisation period.
Writing Improvisational writing is an exercise that imposes limitations on a writer such as a time limit, word limit, a specific topic, or rules on what can be written. This forces the writer to work within
stream of consciousness and write without judgment of the work they produce. This technique is used for a variety of reasons, such as to bypass
writer's block, improve creativity, strengthen one's writing instinct and enhance one's flexibility in writing. Some improvisational writing is collaborative, focusing on an almost
dadaist form of
collaborative fiction. This can take a variety of forms, from as basic as passing a notebook around a circle of writers with each writing a sentence, to coded environments that focus on collaborative novel-writing, like
