The algorithmic elephant

When following the graphic score of Pithoprakta by Xenakis along with the recording, we see the piece is based on mathematical structures that look organic, as if drawn by hand. This organic appearance is valuable in composition. If the strings entered in square orderly fashion, the score would show straight lines, leading to predictable music. Breaking these lines creates more organic shapes and a more organic listening experience. The score remains schematic but features structures as natural as a tree, not a refrigerator. Pithoprakta avoids ideal squared forms, making it more interesting to the ears...

The original analog score by Xenakis has both musical and visual value

 
Pithoprakta: graphical score by Pierre Carré

The music of Xenakisis both organized and visceral. Xenakis breaks the commonplace conception of Apollo as the opposite of Dionysus. The guts of Dionysus and the arrow of Apollo converse. The warmth of wine, the dance, the beast come together with the intellectual distance, the direction, and the predetermination of the archer. Gabriel Valverde, my composition teacher, used to say when talking about Xenakis: "An elephant has passed." An algorithmic elephant, I would say!
 
 
Pithoprakta, score excerpt

I am interested in the mathematical construction of organic forms. Nowadays there are many contemporary composers who work with mathematical forms derived from nature, with sonic results that are generally highly schematic: the translation of data into music seems to be done by pushing a button. Xenakis was overall a musician, deciding what the algorithm means in the realm of music, and filtering them with musical sense: an old school drawing the functions in graph paper. The mathematical sketches are also scores.
In Pithoprakta, the different scenes succeed each other in blocks, conforming the musical structure. These blocks are in dialogue with each other, like "blocks of concrete" or "blocks of gas" or "blocks of fluids".  In the manner of Stravinsky, Gubaidulina, Ustvolskaya, Nono in his string quartet, among others, the discourse in blocks attempts to disrupt centuries of a Western linear narrative discourse. An urgent matter in the mid-20th century. I listen to Pithoprakta with nostalgia, like someone watching a Tarkovsky film. A classic, that blurry dot back then in the 20th century. Good old times.
In my Música invisible for trombone, Water, played by Dalton Harris, I am using the rhythmical structure of water drops to create musical forms to shape musical forms that create a dialogue between determination and indeterminacy. I use the water itself within the pipe mechanism of the trombone: half brass instrumen, half kitchen sink, the trombone becomes a vessel for sounds, air, and water (listen with headphones please! The beginning is very soft).
