Anandabhairavi

Anandabhairavi or Ananda Bhairavi (pronounced ānandabhairavi) is a very old melodious rāgam (musical scale) of Carnatic music (South Indian classical music) and Yakshagana music. This rāgam also used in Indian traditional and regional musics. Ānandam (Sanskrit) means happiness and the rāgam brings a happy mood to the listener.

It is a janya rāgam (derived scale) of the 20th Melakarta rāgam Natabhairavi, although some suggest that it is janya of 22nd melakarta Kharaharapriya.

Its ārohaṇa-avarohaṇa structure is as follows (see swaras in Carnatic music for details on the notations used):

(chathusruthi rishabham, sadharana gandharam, shuddha madhyamam, Chatusruthi dhaivatham, kaisiki nishadham)

It is a sampoorna rāgam – rāgam having all 7 swarams, but it is not a melakarta rāgam, as it has vakra prayogam (zig-zag notes in scale) and uses anya swaram (external note) in comparison with its parent rāgam. The anya swaram is the usage of chathusruthi dhaivatham (D2) in some phrases of the rāgam.

Anandabhairavi ragam is also a bhashanga rāgam, since it uses more than one anya swaram. Anya swaram of a rāgam is the swaram which does not belong to the arohana or avarohana of its melakarta (parent rāgam), but it is sung in prayogams (phrases used in raga alapana, kalpanaswarams).

The three anya swarams of Anandabhairavi are antara gandharam (G3), chatusruti dhaivatam (D2) and kakali nishadham (N3). All of these anya swaras occur only in prayogas (not in arohana avarohana). "G3" occurs in "ma pa ma ga ga ma", and "D2" occurs in "ga ma pa da". Subtler than the first two, "N3" occurs in "sa da ni sa."
