Thanks Simon! That actually helps a lot. I've been doing those excercises with the tongue out and it feels different.
I have to add that I think I have problems with my chest voice. I took some lessons by 2008, when I had no idea how to sing.. and as I was told to "relax" I think I went to the extreme and started to adapt to an airy sound. I have no problems at all with passagio/bridge.. because I tend to sing back, to the pharynx, but I do have problems to produce the sound towards "the mask" and feel vocal folds closure.
Since I started a week ago with my program I have felt a big change in my voice. Now I speak "in chest voice".. before, I felt like I was always in head voice. In fact when I had any long conversation, or talking in the bus or something.. I lost my voice in no time. These days that hasn't happened to me, it's awesome, lol.
It sounds stupid... but I finally feel like a real man, lmao... being able to talk on my chest voice, and to sing there, when I'm not yet tired.
Those lessons I took where very, very helpful.. cus I was trashing my cords pulling chest.. but then I got kind of "obsessed" with tension.. and kinda messed my voice up, lol
