Sounds and Sweet Airs is an excellent book for challenging the traditional, male-centric classical canon, and I expect that chapters will be assigned by music history teachers for a long time to come. The book has reflective essays at the front and back, but most of the book is biographies: each chapter relates the life and works of a woman composer, giving them the same slightly hagiographic treatment long given to music's "Masters." The chapters are more than just an overview of facts; they highlight and explore the ways their society's—and OUR society's—views of women affected their careers, productivity, and relationships. Perhaps the most surprising revelation for me was when Beer pointed out that we know next to nothing about a particular composer's life as a mother, because it's a current expectation to include motherhood in any biography of a woman, whereas in the composer's time, it was considered irrelevant. That doesn't mean it was irrelevant to her, just that people recording this history didn't see it necessary to include in the story of her composing.
Though the title presents the subjects as "forgotten women" and occasionally as "composers you've never heard of," that's, of course, dependent on the background of the reader. I think this book will be fully readable for someone who has never even heard of Clara Schumann. As for me, I'm a musicologist, so I knew of many, but not everyone! I had studied Caccini and Stozzi from a seminar on musical women in the Renaissance, and as one who's dissertation focused on the 19th-century, I was already quite familiar with Hensel and Schumann (though the focus of this monograph gave me new perspective on them!), but I'll admit I'd never heard of Élisabeth Jacquet de la Guerre, Marianna Martines, and Elizabeth Maconchy, which is a real shame. Fortunately, Beer provides a listening list to acquaint the reader to the composers' most successful and/or most characteristic works, as her descriptions often make the reader thirsty to hear them!
Beer has written a wonderful book that should become a standard in any "Intro to Musicology" course, as well as a starting point for research into any of the included composers. The prose is readable, the details relevant and interesting. I learned a lot, and I hope I carry the lessons into my blog writing, thinking about how I present the various aspects—domestic life, childhood, career—of composers of any gender.
