Abstract
This paper traces the development of jazz musical styles by relating those styles to the organization of jazz musicians and the social context of American society. The authors use a theory developed by Flynn and Hay (2012) derived from chaos and complexity science. The Flynn/Hay theory states that social focussing (chaos, complexity or order: SF) is directly proportional to internal structure (differentiation: D) and inversely related to external information (centrality: C). In mathematical terms: SF = D/C.The authors of this paper describe the social focussing of jazz styles in terms of being chaotic, complex or ordered. They then relate the styles of social focussing to the differentiation of the social system of jazz musicians, and the centrality inputs from the surrounding American society. Their results demonstrating that the style of jazz at each period from the late 19th century to the present era, is dependent upon the ratio of d/c.They conclude that the same analysis could be applied to subsystems of the jazz system, including the development of jazz styles in different geographic regions, as well as within each band and even over the career of each musician, in a kind of fractal effect, where the shape of social focussing is the same at each level.

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.
