Improvisation
Encyclopedia
Improvisation is the practice of acting, singing, talking and reacting, of making and creating, in the moment and in response to the stimulus of one's immediate environment and inner feelings. This can result in the invention of new thought patterns, new practices, new structures or symbols, and/or new ways to act. This invention cycle occurs most effectively when the practitioner has a thorough intuitive
Intuition (knowledge)
Intuition is the ability to acquire knowledge without inference or the use of reason. "The word 'intuition' comes from the Latin word 'intueri', which is often roughly translated as meaning 'to look inside'’ or 'to contemplate'." Intuition provides us with beliefs that we cannot necessarily justify...

 activity.

The skills of improvisation can apply to many different abilities or forms of communication and expression across all artistic, scientific, physical, cognitive, academic, and non-academic disciplines. For example, improvisation can make a significant contribution in music, dance, cooking, presenting a speech, sales, personal or romantic relationships, sports, flower arranging, martial arts, psychotherapy, and much more. Techniques of improvisation are widely trained in the entertainment arts; for example, music, theatre and dance. To "extemporize" or "ad lib" is basically the same as improvising. Colloquial terms such as "let's play it by the ear," "take it as it comes," and "make it up as we go along" are all used to describe "improvisation."

The simple act of speaking requires a good deal of improvisation because the mind is addressing its own thought and creating its unrehearsed delivery in words, sounds and gestures, forming unpredictable statements that feed back into the thought process (the performer as listener), creating an enriched process that is not unlike instantaneous composition [with a given set or repertoire of elements].

Where the improvisation is intended to solve a problem on a temporary basis, the 'proper' solution being unavailable at the time, it may be known as a stop-gap. This particularly applies to engineering improvisations.

Music

'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 recognisable 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
