Abstract
The acoustical and perceptual factors involved in timbre blending between orchestral wind instruments are investi- gated based on a pitch-invariant acoustical description of wind instruments. This description involves the estimation of spectral envelopes and identification of prominent spectral maxima or ‘formants’. A possible perceptual relevance for these formants is tested in two experiments employing differ- ent behavioral tasks. Relative frequency location and mag- nitude differences between formants can be shown to bear a pitch-invariant perceptual relevance to blend for several in- struments, with these findings contributing to a perceptual theory of orchestration.

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
