Abstract

fetched live from OpenAlex

Tenor steelpans are unusual, even among percussion instruments, in that all notes share a common surface. This physical coupling between the notes causes complex interactions between notes when activated. In an effort to better understand how these interactions work, we commissioned the building of three custom steelpans with one, two, and four notes instead of the typical 29. The one note pan has a single note in its standard position and the rest of the sunken bowl is empty. The two note steelpan adds a second note one octave higher. The four note steelpan further adds two notes a musical fifth higher. With the reduction in notes, the interactions are minimized and we can see how they affect the timbre of a full steelpan. In this paper, the results of audio feature extraction performed on these custom instruments is presented and compared with the audio features from a full range steelpan. Through this we gain insight into how octaves and fifths affect a note’s timbral characteristics and lead to the attributes of a full steelpan.

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.
