Why does Natalia Osipova, one of the world's best classical, dramatic ballerinas, want to start a sideline in contemporary dance in the middle of her career? Two years ago, when she mounted her first self-commissioned contemporary triple bill with her then newly-ex-fiancée Ivan Vasiliev, I was willing to believe that it was for the love of trying new things, pushing her own boundaries, and taking all aspects of her artform seriously.

I could tell you what the German word "Betroffenheit" means by giving a dictionary definition, etymology and connotations and so on. But I won't, because this dance-drama hybrid by Jonathan Young and Crystal Pite is precisely not about pinning down definitions or making sense through words in a descriptive, iterative sort of way, but about capturing feelings or states of being in a much more metaphorical, experiential, immersive way. Betroffenheit is in one sense, then, the feeling you have after watching the show Betroffenheit.

It shows you just how much Kenneth MacMillan changed ballet in this country that 1960's The Invitation, with its onstage rape, sexual grooming and child abuse, can act as the reassuring classic at the heart of the new Royal Ballet triple bill which opened on Saturday.

From time to time theatre managements hit on the idea that danced drama should be part of their remit. Nick Hytner flirted with it at the National in his day with a run of productions for Lloyd Newson and his company DV8. Now Matthew Warchus, his feet barely under the desk at the Old Vic, has commissioned a show from a young choreographer who has Matthew Bourne’s crown in his sights.

Appearing before theatres full of middle-aged women in just your underpants is certainly one way to throw a retirement party. It may not be everybody's choice, but then Carlos Acosta is not like everybody, and never has been.

Another year, another new full-length story ballet from one of the Royal Ballet's in-house choreographers. Time was – a long time, in fact, up to 2011 – when that would have sounded like science fiction, but no longer: Liam Scarlett, whose Frankenstein premiered last night at the Opera House, is treading a path worn smooth in the past five years by Christopher Wheeldon, Wayne McGregor and Carlos Acosta.

Hearing that both Javier de Frutos and rabbit heads appear in the new BalletBoyz bill might give you pause. A choreographer so unafraid of graphic content that he started his career with naked one-man shows, and later made a piece about the Pope so sexually explicit and offensive that he got death threats – do the rabbit heads mean we're in for some kind of furvert orgy?

On Thursday the Mariinsky Ballet and Orchestra swooped into Cardiff for the ballet company’s only UK dates this year. Appearing at the Wales Millennium Centre for just four ballet performances, plus a family concert of Peter and the Wolf, the Mariinsky’s arrival does seem an extravagant indulgence by its backers, especially with the decision to show exclusively contemporary, Western-style, ballet programmes.

Why are there so few female choreographers? Tamara Rojo, bugged by the fact that in 20 years on the ballet stage she had never danced anything choreographed by a woman, has stopped wondering and started doing something about it. ENB’s latest programme, an evening of three new commissions, sets out to show not only that women dance-makers can be just as accomplished as their better-known and vastly more numerous male counterparts, but also that their work can speak with a distinct voice.

It was twelfth night for Christopher Wheeldon's two-year-old, three-act Shakespearean ballet, and this newcomer had one nervous anticipatory question. The verbal music is gone, only the plot remains, so could A Winter's Tale the play inspire Wheeldon to imaginative heights in the way that Romeo and Juliet brought out the best in MacMillan, via Prokofiev?
