The core pulse of Tudor polyphony is often deliciously slow. It gets down to a mesmeric pace of about 30 beats per minute. The listener just has to succumb to it, and the experience, even in the virtually unheated Cambridge College chapel where The Sixteen began its 2014 Choral Pilgrimage last night, was pure pleasure.

In a Q&A at the London Screenwriters' Festival last year, Welsh writer/director Caradog James and producer John Giwa-Amu already had fans. If that Q&A is any indication, the team at Red & Black Films have a brilliant career ahead of them, all thanks to The Machine, a dark science fiction tale of artificial intelligence and human scheming that is finally released this week.

Handel’s “little opera”, as he called Acis and Galatea when he was composing it in 1718, probably survived while his true, full-length operas vanished from sight precisely because it was little, compact and manageable, like Purcell’s Dido or Pergolesi’s Serva padrona. But little isn’t the same as easy; and these days a production like the one with which Mid Wales Opera is celebrating its 25^th anniversary can find itself asking more questions than it can readily answer

Why has Nordic noir been such an addictive novelty? Yes the plots are great, the locations moodily cool, the flat dialogue enigmatic. But in the end it’s all about gender. The detective who is a genius at work but clueless at life – we’ve seen it all before in a suit and tie and a battered mac. What’s different in equal-opportunity Scandinavia is that the dysfunctional crimebusters are beautiful bug-eyed Valkyries. Up north it’s the blokes who are the sidekicks.

The late rise of Ruth Jones, who has been made an MBE, is a blessed relief. According to the prevailing rules of ageism and lookism, Jones should still be plugging away in supporting roles, typically as the large gobby sidekick which for years looked like the outer limit of her casting range.

There aren't a lot of harpists in pop. Transatlantic migrations took all sorts of instruments away from their European place of origin to become the building blocks of American music. But there was no sizeable Welsh diaspora so the harp stayed at home with its most diligent exponents. That places singer-songwriter-harpist Georgia Ruth in a musical tradition with deep roots but a less than broad reach.

When the term “world music” became a category in record stores, it’s doubtful that triple harps, cerdd dant and canu plygain would have been thought to belong under the umbrella. And yet here they were on display at WOMEX. The annual world music expo has put down roots in Cardiff this year, and to bid welcome to the delegates Cerys Matthews hosted a celebration of traditional Welsh music under the title Gwlad y Gân/Land of Song. Bar the odd burst of Under Milk Wood and a version of "Men of Harlech", very little of it was, for obvious reasons, in English.

Phil Campbell (b 1961) has been guitarist with Motörhead since 1983. That’s four fifths of the band’s 38 year existence. His have been the dirty great riffs at the core of classics such as “Killed by Death”, “Flying to Brazil”, “Eat the Rich", “Stone Deaf in the USA”, “Rock’n’Roll” and multiple others. He has appeared on 15 of their 21 studio albums, including Aftershock, their latest, which initially comes cover-mounted on a special edition of Classic Rock magazine, but receives a full release in late November.

Henry James said, “Realism is what in some shape or form we might encounter, whereas Romanticism is something we will never encounter.” The 19th-century Realists believed that “ordinary people” were “fit to be endowed” with the greatness of imaginative writing. Rachel Trezise’s first stage play, Tonypandemonium, an attempt at kitchen sink par excellence, understands James’ definition; unfortunately it does not seem to understand the second part; that realism is different from mere replication, and that it must belong to artistry.

A fortnight after its release, fans now know the Manics’ latest album Rewind the Film to be a rich, contemplative affair. The musical dynamics are intimate and seemingly best suited to small venues, like the one that features in the video for the single “Show Me the Wonder”. As I made my way across London last night, I wondered if this new sound was why the band had chosen to downsize from last year's O2 to the cosy surroundings of Shepherd’s Bush Empire. Was this "last phase of the band's development" to be consciously close-up and personal?
