Easier with Practice is a film about phone sex based on a short story that appeared in GQ magazine. It’s enough to make any right-thinking filmgoer not in the Will Ferrell/Chuck Palahniuk/American Pie core demographic head for another screen – any other screen.

A 70-minute song cycle for soprano and violin, the Kafka Fragments is the magnum opus (the irony of its miniature forms seems entirely deliberate) of György Kurtág, a composer known for the inscrutability of his music. His lines arrive at the ears fully armed, unwilling to surrender their meaning. A performance of the Fragments at the Tanglewood Music Festival in 2008 famously drove a musically literate audience from the room, so can Peter Sellars's staged interpretation really offer a more engaging experience? Up to a point.

Offbeat in more than just their rhythms, jazz musicians have always had an affinity to the extraordinary, living lives syncopated against the regular tread of society. Maybe it was the informality of their training, or the influence of brothels, bars and back streets that were their concert halls, but the likes of Buddy Bolden and Django Reinhardt have left a legacy of autobiography every bit as bold and unusual as their music. It is in this legacy that Alessandro Baricco’s fictional pianist Novecento claims his share, in a 90-minute monologue that riffs on the unlikely melody of his life to create a beautifully absurdist fable.

It is one of the enduring mysteries of Leon Kossoff’s art. How does someone who uses such thick, impastoed paint and such muddy, earth-toned colours make his work so light, so delicate, so filled with grace? The more you look, the more mysterious is becomes.

When Tony Harrison transposed his version of Molière’s The Misanthrope from the 17th century to the early 1970s, he managed with his characteristic and brilliant combination of savagery and wit to make the play feel totally contemporary. For Andrew Hilton’s new production at the Bristol Old Vic, Harrison has tweaked the play into the 21st century, with characters clutching iPhones and boasting of their connections with Sarkozy. Molière’s masterpiece is about human failings and the reason this classic makes us laugh today is because we recognise ourselves in the characters' parade of foibles.

The business end of 1980s BBC sitcom, the Yes, Minister and Yes, Prime Minister series delivered political body-blows while sporting a dapper suit – satire with a gracious smile. In today’s era of muscled political heavies like The Thick of It, the Jay/Lynn brand of PG humour seems as antiquated as a blunderbuss – particularly when translated to the stage – but with just a few tweaks proves to be surprisingly effective.

Visit the room in the Louvre where the Mona Lisa hangs, and all you will be able to see is a glass-covered rectangle and hundreds of camera phones held high. Certainly you will be unable to examine the woman in the picture, or contemplate the work of the artist who painted her. Yet they - sitter and artist - are, finally, what matters: that one day, the (probable) Lisa Gherardini, wife of a silk-merchant, sat down in front of an artist, who began to paint her.
