“It has a music of its own. It produces vibrations.” Oscar Wilde was being ironic when he had Gwendolen contemplate the sound of her beloved’s drab name in The Importance of Being Earnest, but he had a point when it comes to composers and poetry. With their own “vibrations”, great poems rarely warrant musical interference; bad poetry, meanwhile, can resist even the finest scoring.

A complex Swedish product to unpack, this one. Someone in the BBC must have worked out that it could do with a detailed instruction manual to help people with the task: the programme booklet duly ran to a full 50 pages.

Anyone who came to the National Youth Orchestra’s annual Prom in the hope of hearing some roof-raising feelgood blockbuster might have slunk out disappointed into the tropical night of Kensington. What an ambitious, high-concept menu Sir George Benjamin slated for the teenaged regiment – over 160 of them at full strength – and how confidently they served (almost) all of it.

Sometimes the more modestly scaled Proms work best in the Albert Hall. Not that there was anything but vast ambition and electrifying communication from soprano Anna Prohaska and the 17-piece Il Giardino Armonico under Giovanni Antonini, making that 18 when he chose to take up various pipes (★★★★★). By contrast the big BBC commission from Joby Talbot to write a work for much-touted guitarist Miloš Karadaglić and orchestra in the evening's first Prom left very little impression.

This concert was inspired by the huge scale of the Albert Hall. The three works all evoke spacious vistas, through their expansive textures, echo effects and horn calls.

Children’s concerts are a tricky business, but the BBC has hit on a good formula with its Ten Pieces project, now in its fifth year. Ten works are chosen for their diversity and accessibility, and these become the basis for education projects throughout the year, culminating in the Proms concerts.

Two of the major themes in this year’s Proms season are the hundredth anniversaries of the death of Hubert Parry and the end of the First World War. This programme brought those two ideas together, with two works by Parry himself, along with pieces influenced by the war and written in its aftermath by Parry’s pupils Holst and Vaughan Williams.

Beguiling echoes, patterns and symmetries accompanied the Hallé on this Proms journey through the enchanted forests of orchestral sound.

There’s a particular quality to light seen from shadow. Think of the surface of the water glimpsed, hazy and haloed, as you swim upwards after a deep dive, or the smudged edges of city lights seen from a night flight. This concert by Ben Gernon and the BBC Philharmonic was an exercise in adjusted perspective.

Shostakovich’s First Cello Concerto combines the composer’s usual angst and nerviness with a sardonic humour, right from the opening bars, where the cello and orchestra seem to be playing in contradictory keys. At last night’s Prom, cellist Alisa Weilerstein played the opening motto not as a challenge, but as the continuation of a conversation already in progress. It was also very fast, which issued a different kind of challenge to the orchestra.
