Abstract: 본 발명은 바이얼린 연주나 교습에 있어서 잘못된 활의 밀링자세를 교정하는 교정 기구에 관한 것으로, 지지장치가 공명에 전혀 지장을 주지않는 단계, 기구의 장치와 해제가 한번의 클립(clip)만으로 가능 하도록 하는 단계, 활의 슬립(slip)을 방지하고 손목, 팔, 어깨등의 경직과 자세를 교정하도록 설계된 듀더 의 단계가 있다. 고래(古來)로부터 엘보스담 이라는 임의적 인체 부착형 기구가 쓰여져 왔으나 활의 슬립을 교정 할 수 없는 결정적인 결함을 안고있었다. 
     오늘날 독특한 지도방법에 따라 바이얼린 공명체에 부착하여 자세교정의 노하우(Kow-how)로 사용하는 사사도 더러 있으나 공명감소 외에 장치 및 해제의 복잡성이 사용상의 부담으로 지적되어 왔다. 이러한 문제점에도 불구하고 자세교정기구의 필요성은 초보단계에서는 절대적이며 중급의 단계에서도 매우 효과적이라는 여러편의 논문집들에 이론적 근거를 두고 있다.  현악기에 있어서 활의 밀링은 활의 방향, 의도하는 지각에 따라 손가락, 팔목, 어께등 신체에 힘의 안배가 이루어 지게 되는며, 슬립과 같은 의도하지 않는 간섭현상에 대하여 인체(人體)는 관계된 신체기관에 대응하는 힘을 또다시 전달하게 되는데, 이 과정에서 손가락, 팔목등에 경직(硬直)이 오게된다. 이 팔목의 경직은 연주자로서의 미래를 막는 가장 큰 적인 셈이다.  본 발명은 이와같은 논리(論理)에 근거하여 바이얼린 자세 교정에 중점을 두고 있다.
