The sintir , also known as the guimbri or hejhouj, is a three stringed skin-covered bass plucked lute used by the Gnawa people of Morocco. It is approximately the size of a guitar, with a body a carved from a log and covered on the playing side with camel. The neck is a simple stick with one short and two long goat strings that produce a percussive sound similar to a pizzicato cello or double bass.
