Patayani thappu: India musical instrument

The patayani thappu is an Indian frame drum that has a wooden rim, which is covered with leather on one side. The musical instrument is played with the hands by the player, as opposed to parai thappu that is played with the use of sticks. The thappu is used in the ritual art of Kerala called padayani, in which the musical drum accompanies stylized dance movements and gives percussive music in a rhythmic group. Some of the rhythmic patterns performed are the Champa, Kaarika, Kumba, Adantha and Marma. In the devotional music, the musical instrument is often accompanied by the traditional cymbals called elathalam.
