I wish that Ross had given a little more than a paragraph to Nadia Boulanger. I wish he had mentioned Lili. There are a couple of paragraphs on Ruth Crawford Seeger, with a reference to her biographer Judith Tick, and there is a paragraph about the Princess de Polignac, but there is no mention of Elizabeth Sprague Coolidge. Important 20th century composers like Louise Talma, Joan Tower, Lucia Dlugoszewski, and Ellen Taaffe Zwilich are also overlooked in Ross' 20th century. Germaine Tailleferre's name is mentioned as one of "les six," but Ross does not write anything about her or her music.
I know that there is not space in a book like this for everything, but it would be nice for intelligent people who are new to what I also don't like to call "classical music" to have a sense of the gender equity that started in music during the 20th century, and it would be nice to have the kind of public cultural recognition that will help it to continue.
