Bilahari is a janya (derived) raaga of the 29th Melakarta Dheerashankarabharanam. Bilahari uses the same scale as its parent but omits certain notes in specific phrases, creating its distinctive flavor. Kalyani (65th), Shanmukapriya (56th), and Keeravani (21st) are melakartas but not the parent of Bilahari.
