Panta Rhei (2006) - generative sound environment for Jurgen Messensee
b'Excerpt of an aquatic soundscape for J\\xfcrgen Messensee\'s installation \\u201ePiscina di Venere\\u201d in the rotunda of the Essl Museum in Vienna/Klosterneuburg (Austria) in 2006.\\n\\nInfo: http://www.essl.at/works/panta-rhei.html\\n\\nWater in its diverse aggregate states and forms of flowing is the basic acoustic material for this piece, which is permanently scanned, altered in its corporality and continuously recomposed through a random-based compositional algorithm. Here the form and energy distribution of a wave serve as the fundamental formal principle: the rising and falling of the sounds, the glissando movements and the spectral sound shifts are controlled by a time-variant wave model, the parameters of which are constantly changed by random operations. In this way, a process is set in motion that eludes any kind of external control and is carried out before the ears of the listeners like a natural phenomenon: "panta rhei" - everything flows.'
