I must say I am finally starting to get the slide. I stopped exercising for a month and a half during the holidays Is not something I'm proud of. But I have discovered something now. Since I took a step back I'm seeing I was putting too much pressure somewhere in my system. It turned out to be I was elevating my larynx to sing high notes all the time. Then I remember what Jaime said when I accidentally did my first Power push, keep that larynx low. (It seems that otherwise you can get seriously injured I found out through another source). Every time I sang around E4 for a while my voice will hurt and it was me elevating my larynx.

That is the same reason why I was breaking when transcending into full voice while sliding down on the Falsetto slide. My cords were simply jumping from my larynx going back down when they switched positions. I know Jaime and Valerie mention this but they definitively should tune the text to make more emphasis on this part.

the way the book is written dictates how the method is communicated to the student. personally i think it has been miscommunicated for me. the way he says "stay in full voice" gives the impression that you are supposed to get your chest sound and carry it to the high notes when this is wrong, the voice should zip up, but at first zipping up your voice will sound weak and falsettoish. strangely NO vocal method i've seen explains this fact that your high notes at first will sound falsetto ish until you learn how to add power after zipping. this is a big problem because if you don't tell the student this then they are going to expect to have a chest sound all the way up straight away which isn't the case. you are supposed to start softly and gradually add power over months to years as you get better. if you have to push or strain then your not doing it right.
