The database mainly features intangible cultural heritage including Mongolian long tune, khoomei singing, folk songs and music played by the horsehead fiddle. 

"Statistics show that there are over 100,000 Mongolian music pieces in China, Mongolia and Russia in total, with 40,000 in China, 30,000 in Mongolia and 35,000 in Russia," said Hasbgen with Inner Mongolia paradise grassland media and culture company who is responsible for the database building project.
