Do you see it? Left versus right?
All the women are in static, still poses. All the men are in dynamic poses. Why is this?
I am assuming each dancer selected his and her pose and photo. Are women thinking they must look graceful (and, essentially, passive) and men that they must look active? Why do they think that? IMHO the men's photos are more impressive; I go to the ballet to see movement and their photos make me excited for what is about to come. Creating a balance of strength and grace is difficult and is one of the things I like about ballet, so the men's photos embody that for me (pun intended).
Or, let me get creative here, do men feel more need to prove themselves in ballet, a world which the lay person more naturally associates with women?
Carrying this to its logical conclusion - at least if you are in my head - brings me back to a previous post about how men are raised to have to prove themselves continuously, society does not tell them they have a choice.
To note: this is from the playbill of the Atlanta ballet, the dancer bios.
