What Auden called "the sexy airs of summer" arrived early in Göttingen this year. Frog action in the Botanical Gardens of the town's pioneering University may have been less clamorous than when I first came here in late rather than early May (the annual International Handel Festival usually begins whenever the Ascension Day holiday happens to be, so it's a moveable celebration).

For a festival of wild, genre-colliding musical experimentation, Tectonics is almost starting to feel like part of the establishment. Which shows, if nothing else, that it must be getting somewhere with its boundary demolishing. The 2016 weekend over 7-8 May was its fourth outing in Glasgow – conductor Ilan Volkov founded it in Reykjavík in 2012, and since then it’s spread its all-embracing eclecticism worldwide to Tel Aviv, Adelaide, New York and beyond.

A young nation with a small population and the most untarnished democratic credentials in Europe today can do certain things with festivals not so easy to imagine here. When Estonian Music Days, focused on native and contemporary music, took nature as its theme for 2016 – in this case posing a question in the title, "Green Sound?" – it could expect many of its 60 featured composers to respond to commissioning by making a direct link to the native ecology.

With the death of Sir Peter Maxwell Davies from leukaemia at the age of 81, the UK has lost the most prolific composer of his generation, as well as one of the most passionate advocates for art music.

2016 began with the passing of Pierre Boulez, arguably the doyen of modernism in the field of classical music. Now, only a couple of months later, it is the turn of Nikolaus Harnoncourt, a musician occupying a similar level of singular elevation but this time in what is often described (certainly inadequately in this case) as the "period instrument" movement.

I've never thought of myself as a Shostakovich fan, tending to regard what I know of his output as bleak and forbidding. Photographs of the stone-faced composer with the mortuary attendant's demeanour haven't helped.

The City of Birmingham Symphony Orchestra's appointment of the Lithuanian conductor Mirga Gražinytė-Tyla as its new Music Director won’t have surprised many concertgoers in Birmingham – or indeed regular readers of theartsdesk. The post has been vacant since Andris Nelsons’ premature departure in summer 2015, and the last few months in Birmingham have seen a string of concerts clearly intended as thinly-disguised auditions for conductors of various ages and nationalities.

David Nice writes: 2016 began by ringing in the new with concerts by the ever-astonishing National Youth Orchestra of Great Britain, and continued by ringing out the old-new with funeral bells on the news of Pierre Boulez’s death at the age of 90. Tributes began pouring in from all quarters, including a very pithy one from an old university friend, whom I remember in the early 1980s playing a very young Simon Rattle’s 1977 recording of The Rite of Spring with the NYO and regaling us with stories of how Boulez turned that interpretation on its head within weeks.

So the feasibility study for the new concert hall – The Centre for Music – has finally surfaced, a little later than planned. It’s being greeted, generally speaking, as if it’s to be the next London Olympics. “A global beacon,” declares the Evening Standard... Nicholas Hytner (he who said that building the Southbank Centre extension would spoil the view from his National Theatre) compares it to Tate Modern, which he says enlarged audiences for other visual arts rather than taking them away. This should, he says, be “a Tate Modern for music”.

In 1981 a 20-year-old Swedish trumpeter on national service turned up in the town – city, by Swedish reckoning – of Örebro as soloist in Bach’s Second Brandenburg Concerto. The ensemble, then a mix of amateurs and professionals, some of them from the local military academy, is now the much-recorded and award-winning Swedish Chamber Orchestra; the trumpeter, Håkan Hardenberger, is probably the most famous in the world, and certainly the most adventurous – he still fights for contemporary composers to take first place in musical creation.
