Subclaims¶

q2 i? Bow drift is difficult for learners with BLV to detect in the moment, often being noticed only after sound quality has already deteriorated. → drift-1 q2 i? Many participants over-grip at the frog to avoid losing control, which increases hand, wrist, and forearm tension and reduces fine control. → grip-1

Evidence¶

drift-1¶

q2 · i? · qualitative · r3

Qualitative multi-method study (practice video analysis, lesson observation, interviews) with four violin/viola musicians with BLV. Findings section reports that bow drift is "often noticed only after the sound has already deteriorated."

"Because sound depends on steady friction between the bow hair and the string, small changes in direction or contact point can gradually lead to slipping, scraping, or unstable tone—often noticed only after the sound has already deteriorated."

grip-1¶

q2 · i? · qualitative · r3

Interview and observation data from the same four musicians and three instructors; the article reports "over-gripping at the frog as a protective strategy" that increases tension and reduces fine control.

"Second, many participants described over-gripping at the frog as a protective strategy to avoid losing control. However, a strong grip increases tension in the hand, wrist, and forearm, reducing flexibility and fine control."
