This type of long song is a kind of song, melody and culture of Mongolian Buddhism. Shasdir long song, which was developed and formed centuries ago, has been housed deeply in the life, intelligence, arts and proficiency of the Mongols and was advanced into a larger genre of Mongolian traditional long song. It also influenced the development of Mongolian indigenous aizam long song and has been blended in many aspects. The Shasdir song, sometimes named as ‘Uizen’ long song was developed in correlation to the numeric symbolism of 32 and 33.
