. "The sintir (Arabic: \u0633\u0646\u062A\u064A\u0631\u200E), also known as the Guembri (Arabic: \u0627\u0644\u0643\u0645\u0628\u0631\u064A\u200E), Gimbri or Hejhouj, is a three stringed skin-covered bass plucked lute used by the Gnawa people. It is approximately the size of a guitar, with a body carved from a log and covered on the playing side with camel skin. The camel skin has the same acoustic function as the membrane on a banjo."@en . .
