This piece was made into a ballet by George BalanchineMetastaseis and Pithopraktaalong with the earlier Metastaseis. This was an early example of sonification, in which data is mapped to sonic parameters to be heard rather than read.
Xenakis then transcribed these to musical notation, mapping the particle velocities to frequencies. This article about a classical composition is a stub. Email required Address never made public.

‘Pithoprakta’ by Iannis Xenakis – Music – Contemporary Compositional Practice
Following his architecture work, Xenakis composed works that utilized mathematical and scientific concepts such as architecture, game theory, set theory, and stochastic processes. To construct the seething movement of the piece, he governed the ‘molecules’ according to a coherent sequence of imaginary temperatures and pressures.
Before starting at the university, Xenakis was enlisted in the Greco-Italian war in Thought and Mathematics in Composition The National and Kapodistrian University,— To find out more, including how to control cookies, see here: Fill in your details below or click an icon to log in: Views Read Edit View history.
These ranges differ based on the temperature and pressure of the gas. This page was last edited on 30 Juneat Anastasia Georgaki and Makis Solomos Athens: You are commenting using your WordPress.
Thought and Mathematics in Compositionp. In PithopraktaXenakis divides the work into sections each with their own temperature and pressure parameters and calculates the velocity ranges of plthoprakta particles, according to the Maxwell-Boltzmann law.
The word Pithoprakta translates to “actions through probability”. Pithoprakta is an example of a stochastic work.
Pithoprakta – Wikipedia
This law describes the probable velocity ranges of particles moving within an idealized gas at thermodynamic equilibrium. Examples include bacterial growth patterns, electrical current fluctuation, and—in the case of Pithoprakta —the movement of particles within a fluid. You are commenting using your Twitter account.

A typical performance of the piece lasts about 10 minutes. Leave a Reply Cancel reply Enter your comment here Figure 2 shows the same section from Figure 1, in musical notation. 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.
Notify me of new comments via email. He graphed these calculations with the vertical axis representing the speed of the particle and the horizontal pitholrakta representing time. The lines drawn between the plot points were, therefore, pithoprakat by the instruments playing glissandi between the indicatedfrequencies. The piece is based on the statistical mechanics of gases,  Gauss’s law or Brownian motion. The Harvard Biographical Dictionary of Musicp.
