The music of Tibet reflects the cultural heritage of the trans-Himalayan region centered in Tibet, but also known wherever ethnic Tibetan groups are found in Nepal, Bhutan, India and further abroad. The religious music of Tibet reflects the profound influence of Tibetan Buddhism on the culture. The new-age 'singing bowl' music marketed in the West as 'Tibetan music' is of 1970s US origin. History Western research into the history of Tibetan music has often focused more on religious than secular musics. It has been suggested that Tibetan religious music may have been strongly influenced by West-Asian musics, including those of pre-Muslim Persia (and perhaps even of Byzantium). It has also been suggested that the landscape – and in particular the resonances of caves, with their natural percussive sounding stones - exerted a formative influence on the overtone singing found in Tibetan Buddhist chant (and plausibly also in prehistoric shamanic invocations), which is produced by artful moulding of the oral cavity. The assiduous adoption and evolution of Indian Buddhist traditions and culture in Tibet between the 12th and mid-20th centuries – in a period when Buddhism had disappeared from most of the Indian subcontinent - allowed the Tibetans to perpetuate musical practices from India that would otherwise have been lost, and to develop them in distinctive ways. Although Tibetan religious music can appear quite separate from the major traditions that emerged in Indian music, some of the musical instruments actually descend from Indian monastic and tantric Buddhist contexts, including, for example, the dril-bu hand-bell, the characteristic hour-glass drums called damaru, and the thighbone trumpet (kangling), as used in the practice of chöd. The Lama Mani tradition – the telling of Buddhist parables through song — dates back to the 12th century. The songs were performed by wandering storytellers, who travelled from village to village, drawing on their own often humble origins to relate to people from all backgrounds. Vividly illustrated Buddhist thangka paintings depicted the narrative and helped the audience understand what was essentially a teaching. Tibetan "street songs" were a traditional form of expression particularly popular as a means of political and other commentary in a country that was previously without newspapers or other means of mass communication. They provided political and social commentary and satire and are a good example of a bardic tradition, akin to that in medieval Europe or, more recently, the role calypsos played in the
