Tanboura was a simple type of folk dance performed by a group of men. Historically, it served a social function as it was believed the dancers would exorcise an evil spirit from the target of this dance and was rewarded handsomely. The dance consists of conflicting rhythmic movements and is dominated by a drum beat. An oud and manjur are also used. In modern times, this dance evolved to be used during celebratory occasions such as weddings and feasts. A dance with a similar historical purpose is called Liwa; this dance involves a large flute known as a sirttai, a tin container known as a tanaka, and loud singing.[20]
