What is "garudadhvani"

Garudadhvani or Garudadhwani is a rāgam in Carnatic music (musical scale of South Indian classical music). It is a janya rāgam (derived scale) from the 29th melakarta scale Shankarabharanam. It is a janya scale, as it does not have all the seven swaras (musical notes) in the descending scale. It is a combination of the sampurna raga scale Shankarabharanam and the pentatonic scale Mohanam.
