nicklebleu, beeetlemaniac,
That's interesting, however I cannot determine how strong or weaker the constriction must be, to be required for the pipe breathing because I have to consider the safety/or prolonged strain on the required muscles.
When I tried first the h sound during the introduction video, my cat looked at me like I was hissing. So I guess I don't have the right feedback in this case.
All of the speech pathologists I've trained with, told me that I must not constrict a lot because it could make me lose my voice. The same also applies when speaking, because I find it tiring after a time. For me the production of sounds is not automatic cause I lack the right feedback. The vibrations I feel (on my jaw) during the production of sounds cannot be trusted for determining the sound's range of frequencies. So in this situation I have to monitor about 20 to 25 points of interests in the production of a sound, like air flow, tongue muscle tension, position of various parts of the tongue etc.
I breathe with my diaphragm instead of chest breathing because then my voice is deeper and lower pitched. During meditations I don't breathe thru the mouth cause if I do that, I end up with a very very dry throat.
I've already made my choice, so thank you for your replies. Let's leave the thread to the respective topic.
