In 1992, while in residence at the Banff Centre, Canada, I spent eleven weeks learning to circular breathe so that I could perform Flames Must Not Encircle Sides by Robert Dick. I figured if I could do it at 1.500 meters (ca. 5000 feet) above sea level, in the dryness of the mountain air, I could do it anywhere. I won't forget that first performance so easily! Flutist Aurèle Nicolet was also performing in that concert, so the pressure to perform well was intense.
There is one correction to make on this video: at ca. 01:04 I say "beneath the tongue" when I should have said "towards the base of the tongue".
Michel Debost points out that Circular Breathing should be properly called Circular Blowing. I do believe he is right, but for the sake of consistency and electronic searches, I will keep the term Circular Breathing.
