The next step is to learn to grip the Bansuri in the correct manner and close one hole at a time. In the previous step, when you produced the sound, it was done with all fingering holes open. As you close them one after another, you will produce distinct and clear notes on the Bansuri.
The most important thing to remember while holding Bansuri is that the three fingers of each hand that cover fingering holes, should be free to move quickly on the Bansuri. In other words, these fingers should not be used to grip the Bansuri and you should not force them around it. They should be as light as possible. One of the most common mistakes is to grip the Bansuri with the index finger of the top hand. If you grip the Bansuri with your playing fingers, they will not be able to move fast enough and your playing speed will suffer.
Before you go any further, it is important to point out that the discussion below is my take on the grip. There are many strong opinions and counter opinions in this area. You may want to review them first.
1. the chin
2. thumb of the upper hand pushing the Bansuri at the chin
3. thumb of the lower hand providing counterbalance
Since, by now, you managed to get the sound out of the Bansuri, you can take the next step. Hold the Bansuri with the correct grip explained above with all fingering holes open. Blow into the Bansuri. Make sure that you get the clean sound you got before. Then close the topmost fingering hole. Do you get clean sound of a new note? If so, practice for a while to play with the index finger open and close one after another. You should get notes uniformly spaced in some rhythm – 1,2,1,2,1,2….
Once you can play this comfortably, you are ready for the next step. Close first two holes. Do you get clean sound of yet another note? If you don’t then the most common possibility is that you are somehow letting the air escape from one of the closed holes. Check and try again. Then play to practice opening and closing this hole, so that the notes sound clean and uniform in rhythm – 1,2,1,2,1,2… Then practice to play the three notes that you learnt so far one after the other – 1,2,3,1,2,3… - till you can get the uniform sound and spacing of notes.
Once you get this, close one more hole and repeat one note at a time, till you play with all holes closed. Remember to ensure that you are not letting air leak from any of the closed holes. If you are, then the note will not sound clean.
“The Right Grip” is yet another highly debated topic amongst the Hindustani Bansuri players. Essentially there are two schools of thought. One school of thought – led by Bansuri players following Pt. Pannalal Ghosh’s style - is to close fingering holes with finger tips. This old photograph of Pt. Pannalal Ghosh shows this grip.
Proponents of this approach swear by it and claim several advantages. Some claimed advantages of this grip are – it helps more control on fingering, thereby making it easier to play flat notes. Another claimed advantage is also to be able to close the seventh hole on the Bansuri with the little finger with the lower hand, thereby giving longer range for the slides.
The second school of thoughts – led by Bansuri players following Pt. Hariprasad Chaurasia’s style – is to close fingering holes with the middle part of the fingers except for the third hole for each hand, which is closed with finger tips. This photo of Pt. Hariprasad Chaurasia illustrates this grip. Several advantages are claimed of this grip too. This grip is much more natural for many, especially if you have long fingers. Also, playing Gamaks or continuous slides is much easier.
