It helped me understand the physics of all the process of breathing and phonation in a very graphic, scientific and easy way. I had been doing SOVT Exercises for a while, but this course and Oren's intelligence and easy way to explain it made it so much easier for me to understand and to teach. Thank you Oren. I loved how scientific based this whole course was, I loved how graphic it was, I loved all the explanations and graphics Oren uses, I loved how practical it was and how balanced it was both on practice and theory. I feel so much better prepared to share the knowledge with my students. I understood the difference between training SOVT exercises with or without water. In so many ways. As a singer I can't wait to get my SOVTSTRAW to start working my exercises with it. As a teacher I feel I have so many better ways of explaining why and how all this works for my students. A must take training both as a voice professional - weather you are a singer, a teacher, a voice over artist, a dubbing artist, an actor, a salesperson or simply someone that uses wants to take better care and understanding of his/her voice.
