ABSTRACT

@#BACKGROUND: The limbe is a traditional Mongolian instrument that has been used since the ancient times, and the performer uses a unique method called circular breathing to play it. The circular breathing technique is significant heritage of the Mongolian people, and has been recognized by UNESCO World Heritage. Aim: To study the anatomy and physiology that take part in playing the Mongolian limbe with the circular breathing technique. METHODS: We have studied 20 flutists using case control study method. The flutists’ change of gas compound in blood have been studied with a gas analyzer after playing for 10 minutes with the circular breathing. When the flutists play it with circular breathing, the anatomical structures and their function have been studied and documented by an endoscopy, X-ray and a 320 row area detector CT. RESULTS: The 20 participants were between the ages of 22-56 with the circular breathing experience of 2 to 37 years. After playing the instrument for 10 minutes, we found the following results: 67.7% of the participants developed alkolosis, 23.5% hypocapnia, 5.9% hypercapnia, 94.1% hypoxia, and all participants’ oxygen saturation decreased. The lingual muscles, upper and under muscles of the hyoid bone, larynx and vocal cords are the main structures of the circular breathing. CONCLUSION: Playing Mongolian limbe with the circular breathing leads to hypoxia, thus the circular breathing stops. It is important to note that this process does not depend on flutist’s age, their practice time, and their personal technique. However, we concluded that the time of performance without interruption depends on individual’s physiological characteristics. In order to study the issues of anatomy and physiology that take part in playing the Mongolian limbe with the circular breathing, we have studied 20 flutists using case control study method. The flutists’ change of gas compound in blood have been studied with a gas analyzer after playing 10 minutes by the circular breathing. When the flutists play it with circular breathing, the anatomical structures and their function have been studied and documented by an endoscopy and X-ray. The lingual muscles, upper and under muscles of the hyoid bone, larynx and vocal cords take part in the circular breathing by limbe as a main rule. Playing Mongolian limbe with the circular breathing lead to hypoxia thus the circular breathing stops. This process does not depend on flutist’s age, their practice time, and their private technique. But we concluded that how long time they play it without interruption depends on individual’s physiological singularity.
