The mridangam's name means 'clay body', after the drum's earliest versions

the gist

The mridangam is a two-headed barrel drum that is the main rhythmic accompaniment in Carnatic music from South India. Its name combines Sanskrit words for clay (mrid) and limb or body (anga), because the earliest versions were made of hardened clay. Today it is carved from a single piece of wood, commonly jackfruit, with a different skin on each end and a black paste of iron-rich material on the right-hand head that gives its distinctive tone. In a percussion ensemble it is joined by the ghatam, a clay pot, the kanjira, a small frame drum, and the morsing.

how it works

The two membranes are different sizes and are tensioned by the same straps, so each one vibrates in complex ways. The black paste on the smaller head adds weight at its centre, which shifts its vibration patterns and produces the metallic timbre.

so what

The mridangam does more than keep time: players follow and answer the soloist, improvising within the rhythmic cycles of the music. A version called the pakhawaj accompanies the North Indian dhrupad tradition, and a related drum, the kendang, is played in Southeast Asia.

fun fact

The mridangam is traditionally tied to Tamil Nadu and is described as a royal instrument.
