I have used the Singing Success program for almost two years now. For the first year and a half, I strictly followed all the instructions given by the CDs (dopey lip rolls, for example). I realized the program was actually making me use and develop unnecessary muscles around the neck because the program does not address the topic of WEIGHT enough. I am a baritone and if I were to do dopey lip rolls to start my exercises, I would have so much weight by the end of all the exercises, and my voice would be fatigued. I continued on practicing like this because I believed following their instructions was the only thing I could do.
Then, about half a year ago, I found this forum and the free Singing Success videos. This is where I found Jesse's videos about weight, and how people like me should use neutral larynx lip rolls and that GOING INTO FALSETTO WAS OKAY if my goal was to drop my weight. In the Singing Success CDs, they talked about falsetto as if it's a coordination that will destroy your connection between head and chest voice. This made me fear falsetto and made me pull up chest voice in order to not go into falsetto or flip. But guess what, for a baritone like me, going into falsetto led me to start from a RIGHT FOUNDATION without any weight! I am finally BEGINNING to make progress, after two years. I can finally truly connect from chest to head voice. For tenors, connection isn't too much of a problem because their head voice and chest voice don't have too big a difference in tone, but for people like me, connection is such a hard goal to achieve.
Singing Success should address the topic of weight in more depth. The program would work beautifully for the light voices, but it could be destroying many low voices out there.
