Kedaragaula
Kedaragaula (pronounced kēdāragaula) is a rāgam in Carnatic music (musical scale of South Indian classical music). It is a janya rāgam (derived scale) from the 28th melakarta scale Harikambhoji, and is sometimes spelled as Kedaragowla. 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 Madhyamavati and the sampurna raga scale Harikambhoji. It is a morning rāgam. Structure and Lakshana
