Kettledrums spread with Islamic culture through Africa, Central and South Asia, and Europe. In these areas they are often associated with trumpets as symbols of royal power and status. They are usually played in pairs, with the two drums tuned to different pitches. Large kettledrums may be paired on horses, elephants, and camels in military regiments (including European cavalry and artillery) and civil ceremonies. Smaller instruments may appear in chamber music (e.g., the Indian tabla) and dance accompaniments.
