Abstract

fetched live from OpenAlex

Music software applications often require similarity-finding measures. In this study, we describe an empirically derived measure for determining similarity between two melodies with multiple-note changes. The derivation of our final model involved three stages. In Stage 1, eight standard melodies were systematically varied with respect to pitch distance, pitch direction, tonal stability, metric salience and melodic contour. Comparison melodies with a one-note change were presented in transposed and nontransposed conditions. For the nontransposed condition, predictors of explained variance in similarity ratings were pitch distance, pitch direction and melodic contour. For the transposed condition, predictors were tonal stability and melodic contour. In Stage 2, we added the effects of primacy and recency. In Stage 3, comparison melodies with two-note changes were introduced, which allowed us to derive a more generalizable model capable of accommodating multiple-note changes. In a follow-up experiment, we show that our empirically derived measure of melodic similarity yielded superior performance to the Mongeau and Sankoff similarity measure. An empirically derived measure, such as the one described here, has the potential to extend the domain of similarity-finding methods in music information retrieval, on the basis of psychological predictors.

Teacher imitation

Not 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.
