The nadasvaram is the South Indian version of the North Indian shehnai. Like the North Indian shehnai, it is accompanied by a reeded drone called the ottu. In addition, it is accompanied by the tavil as opposed to the mridangam. This instrument is also known as the nagasvaram, which implies that this is another version of a refined snake charmer.
