Brownian motion is a four-dimensional phenomenon three spacial dimensions and timeand Xenakis created the score by first creating a two-dimensional graph, necessitating some simplifications. Before starting at the university, Xenakis was enlisted in the Greco-Italian war in From Wikipedia, the free encyclopedia.

The lines drawn between the plot points were, therefore, represented by the instruments playing glissandi between the indicatedfrequencies.

Following his architecture work, Xenakis composed works that utilized mathematical and scientific concepts such as architecture, game theory, set theory, and xehakis processes. Figure 2 shows the same section from Figure 1, in musical notation. You can help Wikipedia by expanding it. Pithoprakta is an example of a stochastic work.

This piece was made into a ballet by George BalanchineMetastaseis and Pithopraktaalong with the earlier Metastaseis.

In PithopraktaXenakis divides the work into sections each with their own temperature and pressure parameters and calculates the velocity ranges of theoretical particles, according to the Maxwell-Boltzmann law.

These ranges differ based on the temperature and pressure of the gas.

This article about a classical composition is a stub. He graphed these calculations with the vertical axis representing the speed of the particle and the horizontal axis representing time. An example of this can be seen in Figure 1. Leave a Reply Cancel reply Enter your comment here The National and Kapodistrian University,— A typical performance of the piece lasts about 10 minutes.

The piece is based on the statistical mechanics of gases, [2] Gauss’s law[3] or Brownian motion. This was an early example of sonification, in which data is mapped to sonic parameters to be heard rather than read.
