The mid-way point of the BBC Proms has just passed. Attention during the eight-week season will inevitably tend to gravitate towards the novelties, “events” and one-offs, but one pre-condition for the summer to be going well is that the Proms' backbone ensemble, the BBC Symphony Orchestra, which plays no fewer than 12 of the concerts, has to be on good form. Ideally, they should be playing well across a wide range of repertoire, they should be getting full or nearly full houses, and their relationship with their principal conductor should be positive and productive.

"Let the song speak, I pray," exhorts the Bard in the Prologue to Duke Bluebeard’s Castle, "Listen in silence." This was a night for leaning in and listening closely, despite the large forces arrayed on stage for Dvořák’s Cello Concerto and Bartók’s opera.

In June 2014, I was invited to the late Sir John Tavener’s Memorial Service in Westminster Abbey. It was a poignant occasion, marked by a number of special tributes and performances. My childhood idol Steven Isserlis performed Threnos during the service and as I made my way up to thank him for his moving performance, I was aware he was clutching a big blue score, and talking with Meurig Bowen, the Artistic Director of the Cheltenham Festival.

What makes a musical performance? The final of Young Musician 2016 presented five judges with this philosophical teaser to ponder. For the previous 90 minutes three contestants with three radically contrasting styles of delivery cleared every bar in front of them, with the help of Mark Wigglesworth and the BBC Symphony Orchestra. Giving the nod to one meant the elbow for the others.

Charles Dutoit gets the best from the Royal Philharmonic. He conducts with broad, sweeping gestures, and the orchestra responds with dramatic immediacy and vivid colours. This concert’s programme was well chosen to play to their shared strengths, and the results were impressive: colourful Respighi, muscular Dvořák and taut, compelling Stravinsky.

The Australian musician and musicologist Martin Jarvis, connected with Charles Darwin University in the Northern Territory, has been obsessed for the past 25 years with proving that Anna Magdalena Wilcke, Johann Sebastian Bach’s second wife, was not only muse, inspiration, and copyist but a composer of pieces that now bear her husband’s name. He claimed that she created the cello suites which are among the masterpieces of 18th-century music, among other contributions, including, perhaps, the tune that is the basis for Bach’s Goldberg Variations. 

A memorial concert to a busy man. Alexander Ivashkin, who died last January, was a cellist, a scholar, a teacher, an authority on Russian music, and much else besides. This evening’s concert faced up to the daunting challenge of commemorating the many diverse aspects of Ivashkin’s career. The results were predictably wide-ranging, yet always coherent, and an impressive focus was brought to this mixed but never eclectic programme.

Even the most reluctant of completists should find the prospect of the Beethoven works for cello and piano undaunting. In their totality, these pieces consist of just five sonatas and three sets of variations, which fit neatly on to just two CDs, or occupy two recital programmes. The works are also very important in the early development of the solo cello repertoire. Beethoven biographer Jan Swafford describes the “confident, ebullient, fresh and youthful” sonatas of Op 5 as a genre which the composer, at the time, had “virtually to himself".

Even as orchestras began to sound more and more alike, there was the Czech Philharmonic. And many of its notable characteristics remain to this day: a modest, homespun quality, warm and engaging and full of bright-eyed distinction in the woodwinds.
