No 20th/21st century music aficionados here, huh? I realise this sounds, erm, unfamiliar, but it's actually quite typical for the genre. Just for context, this happened nearly 60 years ago.
Warning - elitist academic wank to follow: it's definitely not mainstream discourse, but there has been a lot of research in feminist musicology and psychoanalysis on the way the female voice is used and portrayed in western classical music, especially on the preponderance of vocalise (wordless singing) in parts written for female singers, eg. coloratura, female vocalise choruses in works by Debussy, say, or Ligeti, or Berio (see "The Great Gig in the Sky for a modern, non-classical example). This is often tied in with a fundamental dichotomy between the voice (corporeal, natural and therefore female, the mother's voice, Kristeva's concept of the chora etc.) and language (Derrida's phallogocentrism, Lacan's nom-de-père). So this does have a background in feminist discourse, albeit rather a niche discourse. The other point would be the characterisation of sirens, the most famous, if not the oldest female singers in western literature, as deadly seductresses. The sirens do not make music in the Apollinian sense, they are not artists, they sing for men and they sing to kill. Combine that with the conspicuous dearth of female composers in Western classical music, and you've got yourself a whole field of feminist analysis.
I'll shut up now.
