Like the Proms, but over a more concentrated time-span, in a much better concert hall and with a swankier audience paying a good deal more, the Lucerne Festival offers a summer parade of the world's greatest orchestras and conductors night after night. Hardly anywhere else, though, offers a home-assembled band of top players quite like the Lucerne Festival Orchestra, even if it will never be the same without Claudio Abbado.

Who is the greatest British conductor in charge of a major orchestra? It's subjective, but my answer is not what you might expect. Jonathan Nott has done all his major work so far on the continent. He left the Bamberg Symphony Orchestra in excellent shape to another of the world's best, Jakub Hrůša; and now he is, as we learned from two long-term players in the Proms Plus talk, liked and respected across the board at the Orchestre de la Suisse Romande.

This should have been the third much-anticipated Prom of the City of Birmingham Symphony Orchestra's inspiring communicator-in-chief Mirga Gražinytė-Tyla. She's now on maternity leave. So those of us who hadn't experienced Ludovic Morlot live before had a chance to witness what a splendid moulder and shaper he is, here in a skilfully co-ordinated all-French programme.

Unanticipated miracles happen every summer in the quiet paradise of Estonia's seaside capital. The first this year came as a total surprise. Having got off the afternoon coach from Riga last Monday and dumped bags at my villa base in Pärnu's garden zone, I headed back into town for the first event.

How do you go about co-ordinating a spectacular like this, the first ever BBC Young Musicians' Prom? With 23 brilliant soloists from clarinettist Michael Collins, not even the winner of the first event 40 years ago, to 16-year-old Lauren Zhang, who stunned us all with her fleet interpretation of Prokofiev's monster Second Piano Concerto this year, commissions or reworkings dealing with batches were the best idea. And all of them worked superbly.

What has 12 hands, 18 legs, 176 keys and two page-turners? Party night at the London Piano Festival, of course. The six-pianist, two-piano marathon on Saturday evening was a high point of this delectable four-day event – though far from the only one.

The first two one-acters in Opera North’s season called The Little Greats were unveiled on Saturday. There are six in all, scheduled on a mix-and-match basis so Leeds opera-goers can choose their own tapas menu: grab one show, choose from various pairs, or even try three on a Saturday (including a matinee) if you want to.

The first day of rehearsals for The Little Greats was thrilling and terrifying in equal measure: the casts of six shows, the whole chorus, all the creative teams and management milling around and talking nineteen to the dozen in the big, reverberant Linacre Studio at Opera North. Old friends, new colleagues – it was like a mixture of freshers’ week and a first night party. The noise was stupendous.

The title of John Adams’s Naive and Sentimental Music is a bit of a tease. Read literally it promises – or threatens – unsophisticated mawkishness, though that is the last thing it delivers. But maybe it was this title, alongside relatively unfamiliar 20^th century repertoire, that kept the audience away. For whatever reason this was the worst attended main Prom I have been to for a long time – and what a shame, as it was also one of the very best.
