See to be very clear to you guys, I have learnt flute from 10 years and still learning it from my guru. I can make you zero to hero in flute. Ask me 100 times about that particular swar, because in online its t oo difficult to listen and understand swar. As all frequency are different. But I always make sure to my every student that learn slowly but perfectly. If you learn directly songs on flute you can't learn flute in deep way. + more - less
