In the Ballets Russes centenary year it’s worth remembering that the iconic Diaghilev ballets were only the few lasting landmarks in a sea of constant novelties and shipwrecks. So if Christopher Wheeldon doesn’t take many great reviews back to the States after Morphoses’ third visit to London, he should be roundly applauded for being so generous to fellow-choreographers and mounting this enterprise in stark times that need initiative more than ever.

Britain’s favourite ballet choreographer Chris Wheeldon rode into his homeland last night, bringing with his Anglo-American company Morphoses work by himself and by Britain’s second favourite ballet choreographer Alexei Ratmansky. Two favourites should be enough to guarantee the opening programme, but there are two drawbacks: the pieces filling the middle of the programme, and the limp video in which it’s all wrapped. And the whole represents a split in taste between US and British ballet expectations from which I am beginning to fear Morphoses - that shining optimistic light of new ballet a couple of years ago - is destined forever to suffer.

Last night was Sun night at the Royal Opera House, when the opening night of the ballet season was supposedly entirely attended by winners of The Sun’s ballet-ballot.

Rubies is a ballet for a girl comfortable with her curves, who can slink her hips and tip her bottom and relish seeing the men’s eyes widen. That the said girl is a ballerina, for whom curves are usually anathema, shows the personality challenge that this snazzy, jazzy George Balanchine ballet sets to its leading lady.

Charlotte MacMillan photographed the Royal Ballet's Mayerling, with choreography by Kenneth MacMillan, music by Franz Liszt, and designs by Nicholas Georgiadis, which opens at the Royal Opera House on Wednesday. The cast is headed by Edward Watson as the death-obsessed Crown Prince Rudolf of the Hapsburg imperial dynasty and Mara Galeazzi as his partner in death, the court groupie Mary Vetsera.

Two ballets are premiered this month with big scientific subjects and new commissioned scores. Birmingham Royal Ballet's David Bintley was inspired by Einstein's principle of relativity, with a Matthew Hindson score, while Mark Baldwin at Rambert Dance Company has been excited by Darwin, with a Julian Anderson score. How does science meet dance?

ISMENE BROWN: How do you think science connects with dance?

The Royal Ballet's leading ballerina Tamara Rojo was holding a large and not old but already battered diary when we met, pages and dried flowers falling out of it, along with notes and photographs. It’s barely a book, more a pile of loose papers, but it is the 10-year diary with which this extraordinary performer, still only 35, intends to see out her dancing career, and move on to her next.

The phenomenal French ballerina Sylvie Guillem (b. 1965) has always been a modern woman, for all her classical ballerina dress. She joined the Royal Ballet in 1989 from Nureyev's Paris Opera Ballet, on terms of strictest independence, hardly saying a word to the press, while her image as a brilliant but truculent "Mademoiselle Non" grew and grew. The image belies the person, though - once you meet her, what’s striking is her lack of side, unblinkered intelligence and polite but firm candour.

In dance heaven, poor Agnes de Mille is resigned to being jostled by nobler colleagues. "Sprightly but peripheral" was her own assessment of her work, yet, with her 1942 ballet Rodeo and her musicals Oklahoma!, Carousel, Brigadoon and more, she invented a genre of popular stage dance that came to dominate the Western public's theatre-going for half the century.

It is a curious feeling to go to meet a hated figure and find a delicate, blonde girl with a sweet face.

On Monday, 23-year-old ballerina Alina Somova opens the batting for the legendary Mariinsky Ballet’s Covent Garden tour in Romeo and Juliet, needing to defy her critics who line up from West to East accusing her of vulgarising the majestic, poised St Petersburg style that defines classical ballet worldwide.
