I think there are fewer women in music than men because women tend to be more practical than men are. They use common sense. Why get a bunch of people together to make noise for a few hours, prance around on a stage, and travel around? What have you accomplished? In the real world, the roof needs fixing, the kids need to get to school, and the lawn won't mow itself. Looking at history this becomes more evident. Why sail across the ocean? You have a home here. Why study what makes things stick to the ground? It works without you knowing why doesn't it? These aren't bad things, just a different thought process. Males, however, tend to have more of a lust for the absurd which has made him responsible for the majority of art and discoveries we enjoy today. A few examples: Christopher Columbus, Lief Erickson, Leonardo da Vinci. This isn't a strictly male trend though. Women have made their input to the arts and sciences as well. Hildegard von Bingen was one of the first people to notate music, Marie Curie developed the theory of radioactivity. On the topic of music, I think its less important who is playing the music than what is produced. A boring band is a boring band regardless of who is in it.
