by the way, not sure if you are correct about composers. You are definitely correct about composers who are featured and given public prizes. In music school, there seemed to be an equal number of women composition students. All the composing professors were men, with one or two exceptions in certain places in the United States. The decision-makers were always men, ultimately. But that is changing today, just like it is slowly changing with conductors. The rank and file had to show it in great numbers first. Mozart's sister was by all accounts a better pianist and violinist than her brother and an exceptional composer. Still she was shoved into manual labor while he was promoted. Clara Schumann may have written some of Schumann's stuff. I do sometimes wonder about Nabokov "not being able to type" and Vera's role in "his" writing. There are countless stories like this in the arts, with the works showing suspicious authorship. It would be interesting to mount a probing investigation into these matter to mine the real data, don't you think?
