'Kali', a Sushir Vadya used in Assam, is considered a more developed version of which instrument?

The correct answer is Shehnai . Key Points The Kali is a traditional wind instrument, categorized as a Sushir Vadya , predominantly found in the musical culture of Assam . A Sushir Vadya (aerophone) is a class of musical instruments where sound is produced by the resonance of air, usually through a reed or a blowing hole. The Kali is structurally and functionally a refined version of the Shehnai , featuring a wooden pipe with several finger holes and a flared metal bell at the distal end. It utilizes a double reed system to produce its characteristic sharp and piercing tone, which is a hallmark of sophisticated wind instruments in the Indian subcontinent. Historically and culturally, the Kali is indispensable in Assamese folk traditions, especially during the Bihu festival, Ankiya Naat (traditional theatre), and various religious ceremonies held in Sattras (monasteries). The evolution of the Kali from basic reed pipes into a more complex melodic tool mirrors the development of the Shehnai in North Indian classical music, making it a critical regional counterpart.
