An interesting discussion. I would like to add that we know from the
discipline of physical therapy that when a muscle is not working properly,
other muscles compensate. That is what limping looks like. That is also
(I conjecture) what some singing sounds like. Some people can be
convincing in their imbalanced vocal production while doing enormous
damage. As for function, each muscle has a primary function, but, (from
what I gather in Zemlin) they work in balance. Spasmodic dysphonia may be
a good example of how neurologic disturbance can cause steadily degrading
vocal function.
By the way, we have only one muscle that opens the glottis-the posterior
cricoarytenoid. I have not read anything about the role of this muscle in
falsetto.
Good chat.
