A Sámi drum is a shamanic ceremonial drum used by the Sámi people of Northern Europe. Sámi ceremonial drums have two main variations, both oval-shaped: a bowl drum in which the drumhead is strapped over a burl, and a frame drum in which the drumhead stretches over a thin ring of bentwood. The drumhead is fashioned from reindeer hide. In Sámi shamanism, the noaidi used the drum to get into a trance, or to obtain information from the future, or other realms. The drum was held in one hand, and beaten with the other. While the noaidi was in trance, his "free spirit" was said to leave his body to visit the spirit-world. When used for divination, the drum was beaten with a drum hammer; a vuorbi ('index' or 'pointer'), a kind of die made of brass or horn, would move around on the drumhead when the drum was struck. Future events would be predicted according to the symbols upon which the vuorbi stopped on the membrane. The patterns on the drum membrane reflect the worldview of the owner and his family, both in religious and worldly matters, such as reindeer herding, hunting, householding, and relations with their neighbours and the non-Sámi community. Many drums were taken out of Sámi ownership and use during the Christianization of the Sámi people in the 17th and 18th centuries. Many drums were confiscated by Sámi missionaries and other officials as a part of an intensified Christian mission towards the Sámi. Other drums were bought by collectors. Between 70 and 80 drums are preserved; the largest collection of drums is at the Nordic Museum in Stockholm. Terminology The Northern Sámi terms for the drum are goavddis, gobdis and meavrresgárri, while the Lule Sámi and Southern Sámi terms are goabdes and gievrie, respectively. , ; In English it is also known as a rune drum or Sámi shamanic drum. The Northern Sámi name goavddis describes a bowl drum, while the Southern Sámi name gievrie describes a frame drum, corresponding to the distribution of these types of drums. Another Northern Sámi name, meavrresgárri, is a cross-language compound word: Sámi meavrres, from meavrit and Finnish ('dig, roar, mess'), plus gárri from Norwegian ('cup, bowl'). The common Norwegian name for the drum, runebomme, is based on an earlier misunderstanding of the symbols on the drum, which interpreted them as runes. Suggested new names in Norwegian are sjamantromme ("shaman
