Results revealed no acoustical evolution in the played violin exceeding the environmental drift observed in the control instruments. Furthermore, kinematic analysis showed no significant drift in the soloist's bowing strategy (bow position, velocity, contact point). These findings suggest that the playing-in phenomenon is driven neither by macroscopic physical changes in the instrument nor by a fundamental reorganization of the player's technique.
That any playing-induced physical changes capable of affecting perceived sound would appear as measurable differences in input admittance or radiated sound that exceed the environmental variations seen in the two stored control violins over the same six-month period (implied in the comparison of Before/After phases and control design).
A controlled longitudinal experiment using laser vibrometry, sound recordings, and motion capture finds no acoustical or kinematic changes attributable to playing-in beyond environmental drift.
