Nadakalyani is a rāgam created by Mahesh Mahadev in Carnatic music (musical scale of South Indian classical music). It is a janya rāgam (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. Mahesh has named the equivalent of Nadakalyani in Hindustani music as Nad Kalyan. Nad Kalyan belongs to the Kalyan thaat of Hindustani music. The first composition in this raga is an ancient Sanskrit shloka Achyutam Keshavam written by Jagadguru Sri Adi Shankara which is composed by Mahesh Mahadev and sung by Priyadarshini.
