Dear Isabelle et al:
I'm just starting to teach Vocal Pedagogy, so I'd like to take a crack at this one. Please, everyone, feel free to correct me or offer differing viewpoints, as I find your input very valuable.
First, you are technically correct in saying that there is no cartilage in the vocal folds (cords), However, the larynx is "built" with several cartilages: the thyroid cartilage, the cricoid cartilage, and the two arytenoid cartilages. These cartilages form a sort of "scaffolding" for the larynx. In my research for the Ped class, I found that some sources also label the epiglottis as a cartilage.
Second, in the Journal of Singing (January/February 2000), Jean Westerman Gregg does indeed point out that the laryngeal cartilages do ossify, or harden, as a person ages.
"The thyroid, cricoid, and the greater part of the arytenoid cartilages are of the hyaline type, which ossifies as the individual matures. The thyroid, and then the cricoid cartilages, start to ossify in the early twenties of one's age, while the arytenoids delay this until the late thirties. These structures are completely ossified by the age of sixty-five (Aronson 1985; Sataloff 1997). The apices (tops) of the arytenoid cartilages do not ossify, because they are made of elastin..." (page 68, Journal of Singing Volume 56, No. 3).
Mrs. Westerman Gregg then goes on to say that adult singers need the strength of the ossified, or hardened, cartilages for the full vocal volumes expected of a mature voice. "It would seem that training of the vocal mechanism takes this long, based on length of time for maturation of the structures, to say nothing of the time required to achieve complete coordination of the muscles, nerves, and so for, for fine, artistic singing." (page 68, Journal of Singing Volume 56, No. 3).
This last statement, along with the continuum of vocal maturation, would seem to explain the pedagogical significance of not "pushing" young voices.
As for your questions about wobbles and hormones, you've got me there. I really don't know very much about that, but I'd love to learn more!
Cheers!
