Ashura ceremony

Besides the original use in war, another use in Persian culture was the Ashura ceremony. Originally in the ceremony, two pieces of stone were beaten on the sides of the mourner with special movements accompanied by a lamentation song. This has been replaced by beating Karbzani or Karebzani and playing sanj and ratchets. Cities where this has been performed include Lahijan and Aran of Kashan, as well as Semnan and Sabzevar.
