Duffmuttu A dance form especial to the Muslim community of Kerala is Aravanmuttu (also called Arbanamuttu), the origin of which can be traced back to the Arabs. It is still accompanied by Arabic music. Aravanmuttu is also called Duffmuttu. The name is attributed to the use of an instrument called duff or tap. Daff is a round percussion instrument with one side covered with hide and is used to produce rhythm. While performing, the leader of the group sings the lead, while the others form the chorus and move in circles. The songs are often tributes to martyrs, heroes and saints. Like oppana, duffmuttu is also staged as a social event during festivals and nuptial ceremonies. Duffumuttu is performed by the male members of the community.
