Abstract
Timbre has been conceived of as a multidimensional sensory attribute and as a carrier of perceptually useful information about the mechanics of the sound source. To date, research on musical timbre has focused on defining its acoustical correlates, whereas fragmentary evidence is available on the influence of mechanical parameters. We quantified the extent to which mechanical properties of the sound source are associated with structures in the data from published identification and dissimilarity-rating studies. We focus on two macroscopic mechanical properties: the musical instrument family and excitation type. Identification confusions are significantly more frequent for same-family instruments. With dissimilarity ratings, same-family or same-excitation tones are judged more similar and tend to occupy the same region of multidimensional-scaling spaces. As such, significant associations between the perception of musical timbre and the mechanics of the sound source emerge even when not explicitly demanded by the task.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
