Training for the oblique part of the cricothyroid muscle

Last time, I introduced training of the cricothyroid muscle using a rubber tube.
This training is a similar exercise, targeting the pendent moiety of the cricothyroid muscle.
The pendent part mostly works using hinged movements. Using dynamic and speedy movements, making it possible to be able to change the voice’s pitch almost instantly.
The cricothyroid muscle has another part though, which is the oblique part. This part assists the cricoid cartilage and the thyroid cartilage, by sliding and extending the vocal folds.
The following photo shows the anatomy of an isolated larynx which is taken from Laryngeal Functional Surgery at the Mayo Clinic in the U.S.A.


They removed ligaments and articular capsules, repaired dislocated joints and moved the inferior horn.
Findings displayed an ellipsoidal dent in the side of the horn, after removing soft tissues of the cricoid cartilage.
This is the glenoid cavity of the cricothyroid articulation.
The black line mentions the outline of the cricoid cartilage and the thyroid cartilage, the blue small eclipse is the glenoid cavity.
The glenoid cavity is very small and movement distance is also very small. The inside of the upper part moves, producing the high-pitched voice.
The cricothyroid muscle moves to the lower part of the thyroid cartilage from the upper part of the cricoid cartilage.
The pendent moiety produces the same movements, but the angle is different.
The penend moiety is vertical and the oblique part is skewed. The penend moiety bends and lift up the cricoid cartilage.
The oblique part moves toward the cervical spine, whilst the cricoid cartilage is in the back.
However, when I tried to repair a singer in a similar fashion, who could not let out a high pitched-voice vey well, it was really hard to diagnose and check the issues over the exterior skin. This is because so many other muscles were moving together at the same time.
When training the oblique part, you have to find the location of the cricoid cartilage first. Then, pinch the side of the cricoid cartilage using your thumb and index finger over the skin tightly. Pull the skin at approximately 2 inches for a woman and 3 inches for a man.
You should not exceed this measurement at the top of the cricoid cartilage when you pull your skin. It must be in the correct position. Then you should let out low pitched vocal sounds.
At this time, please imagine making the shape of your mouth like an “e” sound, while the shape of your lip should look like an “a” sound, and then escalate to higher pitches gradually. If you feel your cricoid cartilage getting in, please pull your skin out with your fingers slowly.
If you pull your skin too strong, you cannot let out a high pitched-voice, because of an obstruction in the sliding of the cricoid cartilage.
I would be very pleased if my guidance helps you to get a good high pitched-voice after trying this brief exercise.


Note: The distance may vary, depending on the person. Please be careful about doing too much excessive exercise in this area. We are not responsible for any accidents or injury which may occur. Please use discretion and take full responsibility for your actions.
