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.
Structure and Lakshana
Garudadhvani is an asymmetric rāgam that does not contain madhyamam or nishādham in the descending scale. It is an sampurna-audava rāgam (or owdava rāgam, meaning pentatonic descending scale). Its ārohaṇa-avarohaṇa structure (ascending and descending scale) is as follows:
The notes used in this scale are shadjam, chathusruthi rishabham, antara gandharam, shuddha madhyamam, panchamam, chathusruthi dhaivatham and kakali nishadham in ascending scale, with kakali nishadham and shuddha madhyamam skipped in descending scale. For the details of the notations and terms, see swaras in Carnatic music.
This raga has shades of western music when played in fast pace. Most of the notes are used without gamaka (without variation of pitch, oscillation around the notes or any analogous transitions between notes).
