Nadaswaram is a South Indian version of the shehnai. It is also called nagaswaram. It is substantially larger than the shehnai and has a simple double reed rather than the more complex quadruple reed. It is considered a very auspicious instrument and is found at temples and at weddings. It is normally accompanied by a sur peti, ottu, and a tavil. There is a smaller version of the nadaswaram which is played in folk music and is known mukhavina.
