The Vienna Improvisers Orchestra dedicates itself since 2005 to the possibilities of the structural organization and switching of musical and except-musical ideas of large ensembles
in the category-spreading context.
Handsigns and other instructions as intercession for musical conceptions between ensemble and conductor are well-known in different musical fields.
In the music of improvising large ensembles these guidances were developed individually in each case (as example I would like to mention Butch Morris),
they determine more and less musical contents and process of the tendentious freely acting ensemble - and enable in addition recipients an inside hearing experience with visual reference points.
The sound/structure and formal feature of the music is carried considerably both by the interactions within the ensemble and for the interaction conductor-ensemble,
why the analytic and integrating work of the conductor is of fundamental importance.
This becomes particularly own, if, as with the Vienna Improvisers Orchestra, the ensemble constellations vary and the guidance of the ensemble can be taken over of
different involved ones.
Cooperating text and music in the context of the improvisation can result in new effect areas and meanings; communication of ensemble and public is the basis
of the formation of a community of the moment.
