Morlam had its birth in the Lao heartlands of Laos and Isan, where it remains a popular art form. Although its precursors probably lie in the musical traditions of the historical Tai tribes that migrated south from China and northern Vietnam, much cross-pollination with indigenous music of the region as well as importation of Chinese, Mon-Khmer, Indian and Malay influences has also had a pronounced affect on the dances, instrumentation and melodies of morlam.
