Professional female violinist performing continuously during...

Professional female violinist performing continuously during the entire clip. The violinist is only playing the violin, nothing else. No singing, no posing, no dramatic gestures unrelated to playing. Right hand holds the bow and performs continuous, realistic bowing motion across the strings, smooth and controlled, perfectly synchronized with the music. Left hand fingers move continuously and precisely along the fingerboard, pressing and shifting positions naturally, realistic vibrato and finger articulation. Hands never stop moving. No idle moments. Clear, deliberate, professional violin technique. The violinist shows subtle body movement and breathing in rhythm with the music — minimal, elegant, natural, not dancing. The violinist looks focused on the violin or slightly downward, calm and concentrated expression. Upper body, violin, bow and both hands are fully visible at all times. Realistic human anatomy, accurate bow grip, correct violin posture, natural hand motion. Camera is fixed, static, tripod-mounted, locked-off shot. No camera movement. No zoom. No pan. No tilt. No shake.
