I'm involved (rather tangentially) in ballet and in the last few days I've seen news items about this dancer shared in an uncritical and celebratory manner. Perhaps, in the past, this wouldn't have bothered me much but now, having lurked here for a bit, it really unsettled me.
I dance, but only in a part-time fashion, for love and self-fulfilment. But even in the most amateur and low key productions, the female roles will be fiercely contested by women who've danced from childhood and have often had professional careers derailed through injury or wayward body shapes. For girls pursuing a professional dream they will be up against hundreds of other talented, dedicated females who are all constantly judged and found lacking: a woman who is too tall won't fit with the rest of the corps and will need a taller partner; and those too stocky, with the wrong sort of muscle development, or with boobs that inconveniently appear in teen years will try to mould (often starve) their body. Comparatively, once the boys have negotiated the social stigma attached to a 'girly' art form, they have many more opportunities. And, after a retiring as a dancer, they are far more likely to get a career as artistic director or choreographer (this is hideously disproportionate).
I admire Tamara Rojo deeply. But this 'opening up' of roles seems to go only one way. I doubt many female dancers have the upper body strength to do the lifts required in male roles so they are unlikely to encroach. Apparently, Chase does not even dance on pointe. I cannot imagine the reaction if a female dancer couldn't / wouldn't do this, but suffice to say, she wouldn't be employed for long.
The worst thing is that the younger girls, still out there grafting for work, are not objecting to this.
