Nata (nÃÂá¹Âa), also known as Nattai, is a rÃÂgam in Carnatic music (musical scale of South Indian classical music). It is a janya rÃÂgam (derived scale) from the 36th melakarta scale Chalanata. It is a janya scale, as it does not have all the seven swaras (musical notes) in the descending scale. It is an auspicious raga, which is mostly sung in the early part of the concert.
There is a raaga named Nata in Hindusthani music as well, and another raaga named Shuddha Nat. But they are sung rarely, and have no association with the Nattai of Carnatic Music. The closest comparable raga to be the Hindustani equivalent of Carnatic Nattai, is the Raga "Jog", which is believed to be a derivative of the Kafi Thaat.
Nata is an asymmetric rÃÂgam that does not contain gandharam and dhaivatam in the descending scale. It is an sampurna-audava rÃÂgam (or owdava rÃÂgam, meaning pentatonic descending scale). Its ' structure (ascending and descending scale) is as follows:
It is a vivadi raga. The notes used in this scale are shadjam, shatsruthi rishabham, antara gandharam, shuddha madhyamam, panchamam, shatsruthi dhaivatam and kakali nishadham in ascending scale, with dhaivatam and gandharam skipped in descending scale. For the details of the notations and terms, see swaras in Carnatic music.
