 The music of Qatar is based on Bedouin poetry, song and dance.Traditional dances in Doha are performed on Friday afternoons; one such dance is the Ardah, a stylised martial dance performed by two rows of dancers who are accompanied by an array of percussion instruments, including al-ras (a large drum whose leather is heated by an open fire), tambourines and cymbals with small drums.Other percussion instruments used in folk music include "galahs" (a tall clay jar) and tin drinking cups known as "tus" or "tasat", usually used in conjunction with a "tabl", a longitudinal drum beaten with a stick.
