Subclaims¶

q2 i? P3–P4 (higher density, higher technical difficulty) showed significantly different curve norms and phase changes versus other passages. → Moura 2023

Evidence¶

Moura 2023¶

Moura, N., Vidal, M., Aguilera, A. M., Vilas-Boas, J. P., Serra, S. & Leman, M. (2023). Knee flexion of saxophone players anticipates tonal context of music. npj Science of Learning 8:22. https://doi.org/10.1038/s41539-023-00172-z

q2 · i? · causal · r1

Wilcoxon signed-rank comparisons (with Bonferroni-Holm correction) of curve norms and phase changes across passages in the expressive condition; the article reports "significant differences in comparing the scores obtained for P4 with regard to the rest of the passages".

"We also found significant differences in comparing the scores obtained for P4 with regard to the rest of the passages (Fig. 1d)."

Discussion¶

Related Claims¶

• Rhythmical density correlates negatively with knee movement amplitude and positively with flexion frequency — a broader claim this one bears on
• Micro-flexions (>1 Hz) occur more frequently in the immobile condition than the expressive condition — related
• Knee flexion causally predicts pitch expectation in expressive playing (Granger causality) — related
