Places, please, deliciousness, please. This is Delibes, a man whose music goes with delectable disbelief, and this is that zany thing, a Fifties nymph ballet, so let us sip hallucinogenic Arcadian cocktails and leave normality at the cloakroom. But the sheer prettiness of Léo Delibes's ballets (La Source, Coppélia, Sylvia) is too much for most dancemakers to digest. Even a choreographer so oozing charm as Frederick Ashton made no classic with his 1952 staging of Sylvia. Last night, given the bumbling performance by the Royal Ballet after a few years’ absence, it came over even more as a ballet best to have on iPod.

“Rudolf thought, what you wanted out of life you had to get straightaway, because if you thought about it too long, you might be dead,” said the ballerina Patricia Ruanne, the first Juliet in Rudolf Nureyev’s version of Romeo and Juliet. Coming a dozen years after Kenneth MacMillan’s landmark Royal Ballet version, Nureyev’s - for London Festival Ballet - is regrettably eclipsed, for what a powerful piece of theatre it is, and this autumn the chance to see both versions side by side has underscored that even if Nureyev was not the greatest choreographer, this was a story about individuals swamped in politics - something he knew about, from experience.

They keep on coming, these screen-to-stage musical adaptations, noisy, bombastic, as unsubtle as juggernauts. The best of them offer up their uncomplicated entertainment with some pizazz; but Flashdance is a particularly vacuous example of the genre. You probably had to be female, and teetering on the edge of your teens, to enjoy Adrian Lyne’s critically derided film back in 1983 (I freely admit that I was, and I did): Tom Hedley and Joe Eszterhas’s screenplay is both shapeless and pointless. This new version, written by Hedley and Robert Cary and directed by Nikolai Foster, does nothing to improve upon it.

What kind of music damages the ears? Hard rock, most people would think, as they sigh at the tinny noise pumping through their neighbour’s cheap earphones on the Piccadilly Line. Even obsessive ballet fans, the kind who spend their last pennies on a bad amphitheatre seat with atrocious sight lines at Covent Garden because Alina Cojocaru is dancing, might not imagine that for musicians sitting in the orchestra pit, the sweeping curves of The Sleeping Beauty might not be quite so romantic. It’s perhaps more obvious with Aram Khachaturian’s score to Spartacus, the ballet which includes a slave rebellion and a wild orgy. But in both ballets, the problem is the same for musicians: the music is so loud, particularly when performed in the enclosed space of the orchestra pit, that it can damage their hearing.

One gin is not enough, not two, or even three gins, to make me susceptible to the idea that John Cranko’s ballet Onegin is anything more than a second-league costume drama with a peachy ballerina role in the middle. But it’s box office, and with Alina Cojocaru and Johan Kobborg in the central roles last night for the Royal Ballet's opening salvo of the season, there wasn’t a hair's-breadth spare in the house, every place gone, even the standing ones in the gods where you can only see a sliver of the stage.

New photographs by Charlotte MacMillan of Russell Maliphant's expanded Afterlight, a mesmerising new dancework premiered at Sadler's Wells this week. The portfolio adds stills from the substantial new sections to ones she took a year ago of the opening solo created for a Diaghilev tribute programme.

We seek it here, we seek it there, we seek it everywhere - that dance work where you lose consciousness of all the hands behind it and surrender to one focus. In Russell Maliphant’s radiant AfterLight, dance, light, sound all move as one, a distilled 60-minute spell of dark, hushed beauty that touches on disturbing things: on ecstasy, madness, desire, jealousy, resignation to the void, and of course on Vaclav Nijinsky.

Sergei Diaghilev was not short of self-belief. He appointed himself the man to introduce European modern art to Russia and then Russian modern art to Europe as the 20th century began, and in doing so he defined himself as the ultimate artistic director, as the remarkable, tentacular exhibition at the V&A Museum that opened yesterday shows. Reviewed elsewhere on theartsdesk, the exhibition's mounting has thrown up extraordinary inside dramas - the telltale paper found in the boning of a 1916 tutu, the unlikely discovery of a stellar bust in a junk shop, and the legendary artists' sweat that no cleaning can obliterate.

Quietly, without pomp and fanfare, Ashley Page has been mustering a balletic strike force over the border in Scotland. Scottish Ballet has launched the new ballet year with a programme that trumps anything else offered in Britain as a season opener, two demanding and brilliant works of the past (well done) and the gamble of a new creation of dance, music and design.

Museum shows don’t often evoke a sense of smell, but without even trying, this Ballets Russes exhibition has visitors’ nostrils flared. The show is – intentionally – a feast for the eye, and even for the ear, with ballet scores (sometimes rudely overlapping) playing in every room. But smell?
