Hi, there, Andante: I attribute all difficulties to
my obliqueness and lack of clarity.

My points were- 1) yes, I believe there to be some bias regarding conducting, and I don't believe it to be limited to "male bias." and 2) the idea that "genius and talent will out" is an attractive one-- we'd like to believe that meritocracy will eventually triumph in these matters, but, (as T.S. Eliot said) "between the conception and the creation falls the shadow." I think we can both agree that there are too many examples of "hype-creation" performers (I'll avoid mention of names here) to believe that the most worthy artists will always emerge from the pack.
As I had an opportunity to reflect further on this topic, I thought about the following:
a) In pre-Elizabethan times, the very finest high-range singers were considered to be castrati and countertenors. We have moved beyond those mutilative times, although (in a case of everything old is new again) countertenors are once again a topic of discussion.
b) Clara Schumann to the contrary, the idea of female virtuosi was considered quite an oddity in the Victorian era. We now have prominent female virtuosi in every solo instrument of note, and rightfully.
c) The idea of all-male orchestras persisted, embarrassingly, until the last quarter-century. The success of integrated orchestras (and the efficacy of screened auditions) have spoken to the benefit of putting that episode in our past.
Finally, at the final threshold of Western Art Music performance, is the idea of the female conductor. So- is there really something intrinsic that will prevent the acceptance of this development, or will this ceiling turn out to be glasswork, like all of the others?
