Nagara

Unlike instruments woven into the melodic texture of kirtan, the nagara's role at a gurdwara is closer to a public bell or a horn: a pair of large kettledrums struck to announce that something is beginning, whether the morning opening of the scripture, a wedding, or a major festival gathering. Its sound is loud, low and carrying by design, meant to reach a community rather than accompany a hymn, and it is typically played in short bursts at the relevant moment rather than continuously through a service.

The instrument itself, a matched pair of hemispherical kettle shells with a stretched hide head, struck with sticks, is shared in form with court and military kettledrums across South Asia, and its adoption into Sikh practice carries that history deliberately rather than by accident, a martial instrument repurposed as a devotional and civic signal rather than one stripped of its original associations. Because that signal function matters more than musical nuance, the instrument tolerates being played by a rotating set of designated seva volunteers rather than requiring a dedicated professional musician, in contrast to the trained accompanists expected for kirtan itself. Gurdwara committees generally schedule its use rather than leave it to spontaneous playing, since an unscheduled drumbeat at full volume can otherwise be mistaken by the wider neighborhood for an alarm rather than an invitation.

Sikh tradition places the nagara's ceremonial adoption in the time of Guru Hargobind, the sixth Guru, who is remembered for articulating the principle of miri and piri, the union of temporal and spiritual authority, and for adopting the visible trappings of a royal court, including a standard, a throne-like seat, and the nagara itself, alongside the specifically devotional life the Sikh Gurus had built before him. Raising a royal drum at a place of worship was a pointed statement in that context, asserting that the Sikh community's spiritual authority did not require it to abstain from the marks of worldly power, a position that shaped how later Sikh institutions understood their relationship to political life.

The instrument has continued in that dual register since, heard today outside major gurdwaras such as the Golden Temple at set times of day and at life cycle events including weddings, where its function remains closer to a public proclamation than to musical accompaniment for the scripture being read or sung inside. The same reasoning is sometimes extended to explain why gurdwara complexes historically maintained a nagara alongside other insignia of authority such as a flagpole and an armory, treating the temporal and the devotional as a single continuous institution rather than two separate domains housed under one roof.
