We’re getting used to expecting the extraordinary from Natalia Osipova - and then getting some more. With her impish face and farouche capriciousness, with a spring like a high-jumper and shoulders like a swimmer, she is without doubt the most explosively delightful comedienne and virtuoso around at the Bolshoi, but could she be a Giselle? A weak-hearted innocent, a sorrowing ghost, an angel of pleading mercy? Doubt it not.

How does a ballerina feel during Swan Lake? Find out instantaneously from the New York ballerina who tweets while she dances. Ashley Bouder is one of the most exciting dancers of the new generation over there - and new-generation she is.

You don’t usually find ballerinas in Monument Valley. Cowboys, maybe, but not a pale, slender girl in a glistening golden tutu alighting like an exotic butterfly briefly on a silk-shod toe in the very same red dust that John Wayne rattled across in Stagecoach. The cover pictures for the Royal Opera House season brochures have fielded some spectacular pictures, but the new spring image is symbolic of the enduring nature of the dancer's will to survive. Sarah Lamb, the translucent blonde from the US, is back on pointe after a year when her career appeared to be over.

There were some odd sights in Christmas Day viewing but none more discomfiting, I’d bet, than seeing a ballerina lying on a physio’s couch having a leg dragged quickly up to touch the side of her head while the other leg lay perfectly still pointing downwards. Can the body really do that? Another weird sight - dozens of people in full 18th-century French costume and wigs dancing in 40-degree heat on a Cuban stage. Meanwhile coachloads of dancers were going down with swine flu and a 45-year-old retired dancer was flown in from Germany to take the part of a 20-year-old.

If Margot Fonteyn and Rudy Nureyev were the most massively important people who ever existed in ballet, then the most massively important question that ever existed in ballet was, did they sleep together? Last night Margot got this over pleasingly quickly. There was the quivery BBC anno at the start that there would be scenes “of a sexual nature”, and hop-skip-jump the couple were at it like rabbits straight after their first performance together.

Critics did not cover themselves with glory after the premiere of The Sleeping Beauty in St Petersburg on a snowy January night in 1890: “We cannot help regretting the means chosen by the theatre directorate in lowering the standard of artistry of our ballet,” wrote one. Another: “Such spectacles attract neither a constant public nor a circle of educated adherents.”

Johan Persson took photographs of Kim Brandstrup's new ballet with Tamara Rojo, Goldberg, which was premiered at the Linbury Studio Theatre, Royal Opera House, on 21 September 2009. Music is J S Bach's Goldberg Variations, designs Richard Hudson, lighting Paule Constable, video Leo Warner for Fifty Nine Productions Ltd, sound Ian Dearden. Performed by Tamara Rojo, Tom Whitehead, Steven McRae, Clara Barbera, Laura Caldow, Tommy Franzén, Riccardo Meneghini. Pianists Philip Gammon and Henry Roche.

At last a seriously good new ballet created not just inside the Royal Opera House’s bunker-like Linbury Studio Theatre but actually making complete sense of its space and atmosphere. Kim Brandstrup’s new creation with the Royal Ballet star Tamara Rojo, Goldberg, is a beautiful, grown-up piece of fine musical feeling and drama, and with a design and lighting scheme to die for.

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.
