The Genesis of GENDY3. The Creative Process that Led to Xenakis' Opus Summum
Bibliographic record
Abstract
Gendy 3 (1991) by Iannis Xenakis is the culmination of his lifelong quest for an automated (i.e. algorithmic) music. About 20 minutes of digital sound are computed directto- disk and presented more or less as such to the public. Therefore, Gendy 3 demonstrates the machine computability of a work of art. Officially, there is only one Gendy 3 in Xenakis' catalogue of works. However, before the world premiere of Gendy 3 on 11/17/1991 in Metz, France, Xenakis presented a proto version called GENDY301 at ICMC Montreal on 10/18/1991, which is a similar but completely different piece. Moreover, an uncut “raw” version (I call it “GENDY3”) can be obtained by re-executing Xenakis' own algorithm. It contains 75 seconds more music than Gendy 3. And finally, Xenakis' algorithm also allows creating a 16-track version by generating all of its 16 layers of sound separately. These 4 versions (2 by Xenakis, 2 by the author), taken together, help to retrace the creative process that led to one of the most remarkable pieces of electroacoustic music to date.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
