Mohanakalyani is a rÃÂgam in Carnatic music (musical scale of South Indian classical music). It is a janya rÃÂgam (derived scale) from the 65th melakarta scale Mechakalyani. It is a janya scale, as it does not have all the seven swaras (musical notes) in the ascending scale. It is a combination of the pentatonic scale Mohanam and the Melakarta raga scale Kalyani. This ragam can be considered as a Prati Madhyamam equivalent of Bilahari, the janya of 29th Melakartha Dheerashankarabharanam. The equivalent of Mohanakalyani in Hindustani music is Bhoop Kalyan or Shuddha Kalyan. Bhoop Kalyan belongs to the Kalyan thaat of Hindustani music. Similar to Mohanakalyani, Bhoop Kalyan is a combination of Bhoop and Kalyan. This rÃÂgam is believed to be invented by Swati Tirunal Maharaja.
Mohanakalyani is an asymmetric rÃÂgam that does not contain madhyamam or nishÃÂdham in the ascending scale. It is an audava-sampurna rÃÂgam (or owdava rÃÂgam, meaning pentatonic ascending scale). Its ' structure (ascending and descending scale) is as follows:
The notes used in this scale are shadjamam, chathusruthi rishabham, antara gandharam, panchamam and chathusruthi dhaivatham in ascending scale, with kakali nishadham and prati madhyamam included in descending scale. For the details of the notations and terms, see swaras in Carnatic music.
