Eighty years ago this summer, Neville Chamberlain’s indifference to the peoples of Czechoslovakia – “a quarrel in a far away country between people of whom we know nothing” – reaped its harvest of total war. These days, we have no excuses for not knowing a lot more. And the opening concerts of this year’s BBC Proms have shown why we should.

A new commission, a Romantic tone poem and a choral spectacular – standard fare for the First Night of the Proms. Traditionally, the First Night sets out the themes for the season ahead, but the rationale behind much of this programme was paper-thin. Janáček’s Glagolitic Mass was included because Henry Wood had conducted it, part of a series featuring pieces Wood introduced to the UK.

Since 2005 Londinium has carved out a niche in the London choral scene as a purveyor of creative programming, exploring often neglected musical byways or making surprising connections and juxtapositions. Last night the idea was a musical Grand Tour of Europe, as taken by aristocratic young men in the 18th century, and a well-crafted and very satisfying concert resulted.

Seven European cities, seven works: from an eight-year-old's First Symphony composed in what is now Ebury Street to the towering concert aria for Josepha Dushchek of Prague's Villa Bertramka, Ian Page's latest Mozart cornucopia took us on a rich and at times startling journey, a testament - as Page wrote eloquently yesterday in his article for The Arts Desk - to the abiding need for freedom of movement in a human being's developm

The festival Summer Music in City Churches is in only its second year, filling a gap left by the demise of the long-running City of London Festival.

Emanuel Ax here celebrated his 70th birthday with an all-Schumann recital. In fact, it was an all-Schumann marathon, a three-hour concert at Wigmore Hall featuring solo works, Dichterliebe with Simon Keenlyside, and, with the Dover Quartet, the Piano Quartet and the Piano Quintet.

Treatise by Cornelius Cardew is the defining work of the graphic notation movement. The score, completed in 1967, is made up of 193 landscape pages, each with two empty musical staves running along the bottom, with an array of graphic designs above, often incorporating elements of musical notation, but rarely specifying pitches or rhythms.

The Barbican Hall hardly boasts the numinous acoustic of Gloucester Cathedral for which Vaughan Williams composed his Fantasia on a Theme of Thomas Tallis, but Sir Simon Rattle has long known how to build space into the architecture of what he conducts.
