A Study on the Living Heritage and Modern Choreography Integration of Mongolian Dance "Shoulder Shaking" and "Arm Flexibility" Techniques from the Perspective of Regional Culture

Abstract

The Mongolian dance methods of shoulder shaking and arm flexibility have major issues of modern inheritance, such as an absence of standard movements, a loss of connection between the traditional approach and the aesthetic of modernity, driven by an over-reliance on static preservation that fails to adapt to contemporary visual languages, and a loss of acceptance by the younger generations. In this paper, the Field Investigation Method (FIM) is used to carry out in-depth interviews with 12 inheritors of intangible cultural heritage in Inner Mongolia and Xinjiang. Quantitative analysis of the frequency (2.8-3.5Hz) of shoulder-shaking and the parameters of trajectory (amplitude 18-22cm) of arm flexibility is done using Motion Capture Technology (MCT), building a three-dimensional teaching system: basic training, cultural awareness, and innovative practice. Comparative experiments show that the teaching group integrating modern choreography techniques achieved a technique mastery score of 82.9, a stage performance score of 76.3, and a cultural connotation recognition accuracy rate of 89.2%. The study proposes a living inheritance path of “core technique protection + aesthetic form innovation + digital recording,” providing theoretical support and a practical paradigm that, while currently utilizing high-precision laboratory equipment, establishes a data-driven logic adaptable to low-cost consumer-grade wearable sensors and mobile vision systems for broader educational deployment. The motion-capture logic can be extended to wearable sensing when high-precision laboratory systems are unavailable.
