ArOhaNa: s r2 g3 p d2 S||
avarOhaNa: S n3 d2 p m1 g3 r2 s||
It is an auDava SampoorNa raaga, with a pentatonic(5 notes) scale in the ascent and a complete descent. It is also a Bhashaanga raaga, (illustrated in the audio) for it borrows anya swara, kyshika nishaada occasionally.
The raaga most often than not operates in the higher octave range and thus opens up the vocal chords and in turn the lungs. Thus the raaga is an ideal treatment for asthma, wheezing and bronchial congestion.
On an emotional plane, the raaga promotes love, tranquilizes a turbulent mind and peps up the mood with its highly energetic notes.
