For deep analysis, scholars often refer to Xenakis’s own book, , which details the mathematical formulas (like the Poisson distribution) used to construct the piece. Iannis Xenakis - Pithoprakta (w/ graphical score)
If you zoom into the PDF, you will notice that the thickness of the lines matters. A thick swarm of lines indicates dense cluster glissandi; a thin line indicates a solo instrument. xenakis pithoprakta score pdf
This graphic approach allowed him to visualize "sound masses," which he later transcribed into traditional notation for performance. You can view examples of these graphic sketches and the final notation through academic resources like ResearchGate or see the work in motion on YouTube with its graphical score .

(1922–2001) was not merely a composer; he was an architect, engineer, and wartime resistance fighter who fundamentally rewired the trajectory of 20th-century music. Among his legendary "stochastic" works, Pithoprakta (Greek for "actions by means of probability") stands as a monument of the avant-garde. Composed in 1955–56, this 50-second-long (or eight-minute-long, depending on your perception of temporal density) work for 46 string instruments, two trombones, and a xylophone is a sonic Big Bang.
The piece begins and ends with distinct sections involving unpitched percussion and string pizzicatos. In the score, these are often represented by blocks of textural instructions or specific symbols for woodblocks and other instruments. The visual contrast between the sparse, pointillist sections and the dense, liquid-like glissandi sections helps the analyst understand the piece’s structural arcs.

Xenakis, having worked as an assistant to Le Corbusier, used architectural drafting tools to compose. The opening pages of Pithoprakta do not use a standard 5-line staff. Instead, they use a Cartesian coordinate system:
