Bilahari

[1] Bilahari is an asymmetric rāgam that does not contain madhyamam or nishādham in the ascending scale.

[1][2] Its ārohaṇa-avarohaṇa structure (ascending and descending scale) is as follows: The notes used in this scale are shadjam, chathusruthi rishabham, antara gandhara, panchamam and chathusruthi dhaivatham in ascending scale, with kakali nishadham and shuddha madhyamam included in descending scale.

For the details of the notations and terms, see swaras in Carnatic music.

This rāgam also uses kaishiki nishadham (N2) as an external note (anya swara) in the descending scale.

This section covers the theoretical and scientific aspect of this rāgam.

Ascending scale with shadjam at C, which is same as Mohanam scale
Descending scale with shadjam at C, which is same as Sankarabharanam scale
