Urtiin duu (longsong)
orig. Mongolia Urtiin duu is a long folk song that originated among the nomadic herders of Mongolia's grassy plains 2,000 years ago. The musical form holds an honored place in Mongolian history and ritual tradition. It is typically performed at festivals and important events, such as weddings, births, the blessing of new homes and the branding of young cattle.
The long, lyrical chant contains 32 verses and is characterized by a wide octave range, frequently falsetto, and a profusion of vocal effects and embellishments. While there are regional differences in the form, it generally features rising and falling melodies and complex rhythms. The singer is often accompanied by the morin khuur, or "horse fiddle."
