It is a kind of song that represents the religious recitation and ritual songs of Mongolian Buddhism and its mantra chants. The Gűr song was developed and formed only since 1750s. Until early 20th century, the Gűr song didn’t undergo sufficient time to reach the entire public in comparison to Shasdir long song. According to long song studies, it’s evident that this type of song was only developed and spread in the vicinity of Buddhist monasteries and centers in terms of the scope of dissemination. However, it’s observed from practice that this Gűr song did influence the heritages of Aizam and Shasdir long songs. For instance, there quite many Gűr songs, including ‘Durtmal Saikhan’ (Iridescent Splendid), one of the most well-known long songs. Gűr song can be considered as a genre of script songs that emerged in the historical progress of Mongolian long songs. The feature of Gűr song is that the methodology of composing Gűr song was dedicated for writing both long and short songs. That’s why, there are many short Gűr songs that have been transmitted as ‘Folk songs’ in addition to the heritage of Gűr long song. The Gűr long song that brought a new breath to the development of Mongolian long song in its history is mainly related to the numeric symbolism of 32, 64, 72 and 86.
