Gambhiranata is a rÃÂga in Carnatic music (musical scale of South Indian classical music) and Yakshagana where it is called Naati. It is an audava rÃÂgam (or owdava rÃÂga, meaning pentatonic scale). It is a janya rÃÂga (derived scale), as it does not have all the seven swaras (musical notes). Gambhiranata is also known as Shuddha Nata.
Gambhiranata is a symmetric rÃÂga that does not contain rishabham or dhaivatam. It is a pentatonic scale (audava-audava ragam in Carnatic music classification â audava meaning 'of 5'). Its ascending and descending scale structure (') is as follows:
The notes used in this scale are shadjam, antara gandharam, shuddha madhyamam, panchamam and kakali nishadam (see swaras in Carnatic music for details on below notation and terms). Gambhiranata is considered a janya rÃÂgam of Chalanata, the 36th Melakarta rÃÂgam, though it can be derived from 8 other melakarta rÃÂgams, by dropping both rishabham and dhaivatam.
Gambhiranata rÃÂgam lends itself for elaboration due to the pentatonic nature and symmetricity of the scale. The mallari tune played in Nadhaswaram at temple processions are set to this musical scale. Here are some compositions set to this scale.
Gambhiranata's notes when shifted using Graha bhedam, yields another pentatonic rÃÂgam, Bhupalam. Graha bhedam is the step taken in keeping the relative note frequencies same, while shifting the shadjam to the next note in the rÃÂgam. For more details and illustration of this concept refer Graha bhedam on Gambhiranata.
