[Mefisto dance scene from TechnoFaustus]

for vibi, player piano, harma, klung, piperola, autosax, springers, rotomoton, vox humanola, belly, bourdonola, qt, xy, casta uno, casta due, invisible instrument and 1 to 3 naked techno or break dancers

duration: 7''00"

In this act, the invisible instrument invented by the author is used to retrieve gesture information from the movements of 1 to 3 dancers. The tempo (BPS 240 to 480) is derived from the speed of movement of the dancer(s). The sound levels of the different automats in the orchestra are functions of the amount of body surface in movement.

Both the Sonar and the Radar version of the invisible instrument can be used. As of 2014, the ii_2010 doppler sonar version is the first choice.


In the Technofaustus production this interlude can be performed and mounted either as a solo triumph-dance by mefisto (older male dancer), or as a trio techno ballet (3 female dancers).
