Abstract

fetched live from OpenAlex

Two of the most salient features of music are the blending of pitch and the matching of time. I propose here a possible evolutionary precursor of human music based on a process I call “contagious heterophony”. Heterophony is a form of pitch blending in which individuals generate similar musical lines but in which these lines are poorly synchronized. A wonderful example can be found in the howling of wolves. Each wolf makes a similar call but the resultant chorus is poorly blended in time. The other major feature of the current hypothesis is contagion. Once one animal starts calling, other members of the group join in through a spreading process. While this type of heterophonic calling is well-represented in nature, synchronized polyphony is not. In this article, I discuss evolutionary scenarios by which the human capacity to integrate musical parts in pitch-space and in time may have emerged in music. In doing so, I make mention of neuroimaging findings that shed light on the neural mechanisms of vocal imitation and metric entrainment in humans, two key processes underlying musical integration.

Not 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.
