This group of long song has been widespread in the territory of former Durvut Dalai Khan county or the Mongol Altai mountain range and the basins of Depressions of Great Lakes. The heritage of aidam and shasdir long songs of Bayad, Durvut, Zakhchin, Uriankhai, Őőld, Torgut, Myangad and Khoton is the main part of the Oirat Mongols long song. It has also been preserved partially among Mongol ethnic groups such as Torguts of Khovog Sair and Bor Tala in Xinjiang, Khoshuuds in Kokonor, and Torguts and Khoshuuds in Inner Mongolia, China and Kalmuks in Volga River, Russia.
Among the long song melody, singing proficiency, methods and techniques of Oirat Mongol group, the most advanced ones are the long song singing styles of Őőld and Myangad ethnic groups. The aidam song of Khoshuuds among Torguts and the long songs of Zakhchin and Bayad would follow. the most ancient form that has preserved the calls that imitate natural sounds such as howling of wolves and bellowing of stag is the ritual long songs of Durvut and Uriankhai ethnic groups. Some of long song heritage reflects the influences of Khalkha long song. For instance, some of the ritual long songs have a widespread tradition of ‘turleg’ (chorus) singing.
In common, the Oirat long song singers have the techniques to sing ‘ulin shurguulakh’ (literally meaning ‘inserting pitches by howling’) or the singing resembling the howling of wolves. The accent of ‘k’ consonant of Mongolian language and the succeeding ‘g’ – occlusive velar consonant of are dominant in phonation- ‘egshig tomolt’ (lit. ‘vowel twisting’ – usage of different vowels in tone shifting in melody) of Oirat long song. Therefore, the Oirat Mongol long song sounds quite energetic and explosive, sometimes quite tough. The melody is quite abridged and has vertical composition, thus has less diapason than Khalkha long songs and it’s often sung by reaching higher or highest pitch by ‘ulin shurguulakh’ (literally meaning ‘inserting pitches by howling’) technique making an effect of echoing in Altai rocky mountains
