While countertenor soloists largely disappeared in the 1930s, from the 1890s-1920s, they were at the top of American popular culture. Publisher Edward Marks recalled that “they had a practiced quaver in their high, pure, almost soprano voices that served them for years.” Boy sopranos were also immensely popular and publishers employed them as song pluggers; their beauty and charm, as well as their affecting portrayal of the song’s narrative, was essential to selling sheet music.

The gender ambiguity of his voice, specifically its “feminine” register, is always a prominent thread in discussions on websites ranging from YouTube to gay-specific blogs such as Towleroad, and this femininity is almost always framed as a problem (“he’s got a good voice, but he sings like a girl” or “he’s the worst gay stereotype”).

“Defying Gravity” both reflects Kurt’s character and transcends him, presenting the feminine male voice, as, quite literally, defiant.
