The dholak is a two headed drum commonly used in folk, popular music, bhajans, and qawwalis, with limited classical capabilities in serving as a nagara replacement for shehnai performances. It is wooden drum having two heads made of leather. Traditionally, it is fastened with rope tying both heads together, in addition to another external rope which allows one to wear the drum while standing. Now, nut and bolt version is not uncommon. Unlike pakhawaj and tabla heads that are multilayered and contain syahis (black center layers of iron for sound control), the dayan (smaller head, shown in the left) contain no syahi, while the baya (bigger head shown in the right) contains a thick layer of tar and clay on the internal surface.
