Watch the Hamsadvhani Raga online guitar lesson by Fareed Haque from Gaga for Raga
I first heard this raga at a performance with the great Bansuri player Hariprasad Chaurasia.
The Bansuri is the Indian bamboo flute and it is a magical, mystical sound especially in the hands of a master like Hariprasad!
One tip I can give you from personal experience: As jazz musicians or rock musicians we tend to always add more spice to our scales. The essential idea of the raga is the mood it creates by staying absolutely in the raga. Any additional notes - even notes in the same key - can ruin the hypnotic character. Don't play any extra notes not the chromatic or diatonic until you really, really, really understand the sound and the spirit of each raga!!
Hamsadvhani is a raga which is popular in both the Carnatic (South Indian) and Hindustani (North Indian) tradiitons, It is a pentatonic raga, using only natural notes. Hamsadvhani in an evening raga, that conveys the mood of happiness and well being. Some feel that it invokes a picture of ducks swimming across a pond.
