Nagasvaravali
# Nagasvaravali

Nāgasvarāvaḻi, is a rāgam in Carnatic music (musical scale of South Indian classical music). It is an audava rāgam (or owdava, meaning pentatonic scale). It is a janya rāgam (derived scale), as it does not have all the seven swaras (musical notes).

## Structure and Lakshana

Nāgasvarāvaḻi is a symmetric rāgam that does not contain rishabham or nishādam. It is a pentatonic scale (audava-audava ragam in Carnatic music classification - audava meaning 'of 5'). Its ārohaṇa-avarohaṇa structure (ascending and descending scale) is as follows (see swaras in Carnatic music for details on below notation and terms):

* ārohaṇa : S G₃ M₁ P D₂ Ṡ
* avarohaṇa : Ṡ D₂ P M₁ G₃ S

(the notes used in this musical scale are shadjam, antara gandharam, shuddha madhyamam, panchamam, chathusruti dhaivatam)

Nāgasvarāvaḻi is considered a janya rāgam of Harikambhoji, the 28th Melakarta rāgam, though it can be derived from other melakarta rāgams, Chakravakam, Sooryakantam, Shankarabharanam, Vagadheeswari or Shoolini, by dropping both rishabham and nishādam.

### Graha bhedam

Nāgasvarāvaḻi's notes when shifted using Graha bhedam, yields another popular pentatonic rāgam, Hamsadhwani. Graha bhedam is the step taken in keeping the relative note frequencies same, while shifting the shadjam to the next note in the rāgam. For more details and illustration of this concept refer Graha bhedam on Hamsadhwani.
