The lines drawn between the plot points were, therefore, represented by the instruments playing glissandi between the indicatedfrequencies. In PithopraktaXenakis divides the pithoprakya into sections each with their own temperature and pressure parameters and calculates the velocity ranges of theoretical particles, according to the Maxwell-Boltzmann law.
