Check out my blog about my experience with The Balanced Embouchure (BE for short). I've been a happy BEer now for 8 years. BE gave me great range & endurance. Since I introduced BE to the French horn Community in 2007, it's become popular all over the world. See my blog. http://beforhorn.blogspot.com/2009/10/hello-and-thanks-for-stopping-by.html
