LDP (Larynx Deep Position) deteriorates the ability to control breathing. This lack of control can be especially noticeable and reported by musicians who play wind instruments, to whom controlling breath is a key factor in making their music.
An experienced Clarinetist recently asked me, “What could be the reason why I couldn’t, all of a sudden, control my breathing when playing clarinet the other day? I’ve never had a problem before.”
I examined him and determined that he has LDP, which caused the omohyoid muscle to go up.
When I moved his larynx by hand, it made a clicking sound.
The following order of issues will happen if you play clarinet (or really any woodwind instrument) with LDP.
1:The arytenoid cartilago corniculata is pressured by LDP.
2:The arytenoid cartilage will forcibly slide and rotate.
3:The glottis opens and breath leaks out.
4:It will become hard to control breathing. Breath is going in through the nasal cavity, while breath is slowed or stopped from entering by way of the mouth/oral cavity.
The black arrow shows the vector of LDP, and the red arrows show the vector of the cervical spine. As a result the blue arrow, which highlights The arytenoid cartilage, forcibly slides and rotates.
Note1:The arytenoid cartilage is moved by sliding and rotating, creating a double action, similar to the action of a temporomandibular joint and cricothyroid articulation.
Note2:Generating sound by clarinet or any other woodwind instrument is really similar to the process of generating human voice.
