Debussy is having a good year. It is wonderful to see such wide and varied celebrations of his life and work, and to let the century since his death bear witness to the huge influence he has had on writers in every field of music.

There is a tide in the best-planned festivals that comes in and out almost imperceptibly, bringing with it changes as the days move on. Put it down to the kind of perfect planning that discards any one rigid theme, and to forging long-term links with performers who don't just pop in for one concert.

With – unusually – no visiting orchestra at this year’s St Magnus International Festival in far-flung Orkney (the fall-out from delayed funding confirmations, we’re assured), there was a danger that the annual midsummer event might have felt a little – well, quiet.

Have you ever wondered why the Steinway grand piano is invariably the instrument of choice in every hall you visit, great or small? Why do the halls in question not offer a choice between two or three pianos of different manufacture, as so many did before the Second World War?

"Get those creatures off the stage, or I won't answer for what I'll do". The exclamation of the Prima Donna in the backstage prologue of Richard Strauss's Ariadne auf Naxos, about to share her grand opera with lower forms of theatrical life, seems to have been shared by a head teacher at the first Setúbal Music Festival in Portugal eight years ago, faced with the arrival of special-needs children to join his pupils. It was a sink-or-swim moment, but artistic director Ian Ritchie stood firm, and the festival has gone swimmingly ever since.

I started singing when I was nine years old in my primary school choir. I sang plenty of solos there before moving on to another children’s choir; that was a formative experience for me. At this point, I was singing the soprano part and from here I was invited to sing in Mozart’s The Magic Flute. This was my first experience of opera, and one that gave me great joy and satisfaction.

Ryuichi Sakamoto has conquered underground and mainstream with seeming ease over four decades, never dropping off in the quality of his releases. Indeed his most recent projects, following his return to public life after treatment for throat cancer in 2014-15, are among his best.

STOP PRESS (10/4/2020): this performance is up for a short period on the Deutsche Kammerphilhamonie's website for free viewing. Paavo Järvi is offering a live Q&A on conducting Brahms on Saturday 11 April 2020.

Held annually every Holy Week, Kraków’s Misteria Paschalia is one of the continent’s most vibrant early music festivals. With an increasing focus on international collaborations, the 2018 edition welcomed Edinburgh’s Dunedin Consort as artists in residence, and their director, Professor John Butt, as Resident Artistic Director.

Anyone passionate about great conducting would jump at the chance to hear 89-year-old Bernard Haitink giving three days of masterclasses with eight young practitioners of the art, his eighth and possibly last series in Lucerne (though he's not ruling anything out). That was the hook to visit this year's Easter Festival.
