This thesis investigates movement efficiency in cello warm-up practice from a practice-based perspective, with the aim of reducing physical strain and improving sound production.

Playing-related musculoskeletal disorders (PRMDs) are widely reported among professional string players, yet preventive strategies remain limited and insufficiently tailored to individual physical characteristics. Traditional warm-up routines tend to emphasize technical standardization rather than physiological adaptability, often resulting in unnecessary muscular tension and reduced endurance.

Through a long-term practice-based study conducted over five years following a wrist injury, a structured warm-up program was developed focusing on posture, bow control, and left-hand touch. The research highlights the relationship between efficient physical use and tonal clarity, examining fundamental variables such as bow angle, contact point, pressure, and speed, alongside left-hand pressure, release, and vibrato coordination.

Rather than proposing a universal method, the study emphasizes adaptable guidelines that support injury prevention and sustainable performance. Findings demonstrate that efficient sound production emerges within a narrow threshold between excess and insufficiency- where minimal effort enables both physical sustainability and expressive flexibility. This approach situates warm-up practice not merely as preparation for performance, but as a pedagogical framework that integrates awareness, efficiency, and long-term health in cello playing.
