Having a strong company style is usually no bad thing, especially if – as with San Francisco Ballet – the main component of it is a commitment to excellence. It has been impressive watching the gritty energy with which, night after night, the American visitors to Paris dish up meaty triple bills (most pieces coming in at 35 minutes or longer) and serve them with éclat. Polish and professionalism like this help dancers keep going through a gruelling tour, and ensure audiences go away happy. But you can have too much of a good thing.

Ballroom dancing, that most civilised of pastimes, may seem an unlikely target for controversy, but a proposed rule change by the British Dance Council (BDC) has thrust our nation’s waltzers into a heated debate. This weekend, the BDC will discuss whether or not to approve a suggested amendment declaring that a ballroom partnership be recognised as “one man and one lady in all adult amateur and professional competitions and championships unless otherwise stated”.

In 2005, San Francisco Ballet were the first company to visit Paris as part of a new summer dance festival, Les Étés de la Danse. Helped not only by this auspicious start, but by the obvious demand for live dance in a month traditionally barren for the Parisian performing arts, the festival prospered, and in this its 10th year, has brought the Americans back with a stonking programme. Every night of the 17-date run at the Théâtre du Châtelet features a different triple bill, covering in total 18 pieces by twelve choreographers – and that’s not counting the opening gala.

La Bayadère is one of the ballets I recommend to people who have never seen ballet before. It has high drama, exquisite tragedy, fabulous costumes, one of the best "white" acts going, and it almost passes the Bechdel test. Sitting in a mostly empty Vue cinema in Harrow watching last night’s live broadcast from the Mariinsky Theatre in St Petersburg, I had a chance to try my own prescription.

This is the heart-wrenching time of year when dance school students give their graduation performances and professional dancers bow out at the end of their careers. How poignant to watch Paris Opéra Ballet étoile Nicolas Le Riche, alone on the vast Palais Garnier stage, bidding farewell to his fans at 42, and then to witness Royal Ballet School youngsters making their debuts en masse at the Royal Opera House.

Bakst’s harem drapes and Roerich’s smoking, steaming Polovtsian camp may not have had the most lavish of recreations. But the rest of this homage to Diaghilev shone with an exuberance and even a precision one would not have thought possible from previous seasons of what had once seemed like Andris Liepa’s Ballets Russes vanity project.

Rimsky-Korsakov’s bizarre final fantasy, puffing up Pushkin's short verse-tale to unorthodox proportions, has done better in Britain than any of his other operatic fairy-tales. That probably has something to do with its appearance in Paris, six years after the composer’s death in 1908, courtesy of a brave new experiment marshalled by that chameleonic impresario Sergei Diaghilev.

No one could accuse Nederlands Danse Theater choreographers Sol Leon and Paul Lightfoot for thinking inside of the box. And yet that's exactly where they've placed their dancers in the opening piece, Sehnsucht, of this impressive Sadler's Wells program.

There are all sorts of companies and shows out there that claim to “rock” the ballet, or otherwise shake up, take down or reinvent an art form that, they imply, is (breathe it softly, the dirty word) elitist, or at least irrelevant. Few, I’d imagine, perform this operation with anything like the skill and intelligence of Dada Masilo, whose 2010 version of Swan Lake opened the lively short smorgasbord season that Sadler’s Wells are calling their Sampled festival. 

In the midst of ferment as the arts world faces fast-shrinking public subsidy, Sir John Tusa, former managing director of the BBC World Service and the Barbican Arts Centre, publishes this week a brisk new book that urges arts and politicians to reject the emotive clichés and lazy token battles and focus on what matters. In Pain in the Arts, Tusa urges that both sides take personal responsibility for an essential part of human life.
