brownian motion

( >> N’Shima)

Brownian motion is a mathematical model used in order to describe the movement of particles inside fluids. Although the motion of the particles is described from various ‘brownian equations’ it can not be predicted. Therefore Brownian motion can be used in order to produce randomness.
Xenakis is employing Brownian motion in N’Schima in the context of stochastic process that he constantly applies in his compositions as the means to create randomness. In N’Schima Brownian motion is defining the glissandi that the various instruments are following.
