Jhankaradhvani or Jhankaradhwani (pronounced jhankÃÂradhvani) is a ragam in Carnatic music (musical scale of South Indian classical music). It is the 19th Melakarta rÃÂgam in the 72 melakarta rÃÂgam system of Carnatic music.
It is called JhankÃÂrabhramari in the Muthuswami Dikshitar school of Carnatic music.
It is the 1st rÃÂgam in the 4th chakra Veda. The mnemonic name is Veda-Pa. The mnemonic phrase is sa ri gi ma pa dha na. Its ' structure (ascending and descending scale) is as follows (see swaras in Carnatic music for details on below notation and terms):
(the notes in this scale are chathusruthi rishabham, sadharana gandharam, shuddha madhyamam, shuddha dhaivatham, shuddha nishadham)
As it is a melakarta rÃÂgam, by definition it is a sampoorna rÃÂgam (has all seven notes in ascending and descending scale). It is the shuddha madhyamam equivalent of Shamalangi, which is the 55th melakarta.
JhankÃÂrabhramari is the 19th Melakarta in the original list compiled by Venkatamakhin. The notes used in the scale are the same, but the zig-zag usage of notes in both ascending and descending scle (vakra prayoga) is the difference.
Jhankaradhvani has a few minor janya rÃÂgams (derived scales) associated with it. See List of janya rÃÂgams for full list of rÃÂgams associated with Jhankaradhvani.
A couple of compositions set to this musical scale are:
This section covers the theoretical and scientific aspect of this rÃÂgam.
Jhankaradhvani's notes when shifted using Graha bhedam, yields 2 other minor melakarta rÃÂgams, namely, Ratnangi and Gamanashrama. 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 further details and an illustration refer Graha bhedam on Ratnangi.
