How to play Komal swara flattened notes) on Bansuri (bamboo flute)

This is the 3rd video I recorded with Rakesh Prasanna, where he demonstrates how to play flattened notes on the bansuri. Basically you need to cover half a hole to get the flattened note. He suggests starting with easier Ragas where there is just one flattened note and then progressing on to 2 flattened notes and so on. Nat Bhairav ( a morning Raga) uses the major scale with a komal Dha (flattened 6th) This by no means easy and requires much practice. Thanks to Rakesh for his permission to upload these cli
