Not many people write conspicuously brilliant tweets, but Elizabeth Watts is someone who does. Working on the most demanding aria on her stunning new CD of operatic numbers and cantatas by the lesser-known of the two Scarlattis, father Alessandro rather than son Domenico, she tweeted: “Good news – I can sing 88 notes without a breath. Bad news – Scarlatti wrote 89.”

Final thoughts: a fitting theme for the farewell concert of this year’s Gewandhaus Barbican residency. But the connections proved tenuous: Death and Transfiguration, the gloomy opener, was written when Strauss was only 25, and the Mozart Clarinet Concerto which followed, while it was one of his last works, shows little concern for mortality or summation. But the motivation was honourable – to find homes for Strauss’ tone poems, which rarely fit comfortably in any concert programme.

In practice as well as in prospect, the second in Riccardo Chailly’s Strauss/Mozart trilogy was a concert of two very different halves. The first offered small Bavarian and Austrian beer in the shape of Strauss’s fustian Macbeth, unbelievably close in time to the masterly Don Juan which blazed on Tuesday, and a pretty but just a little too anodyne Mozart violin concerto at the other end of Mozart’s prodigious composing life to the last work for piano and orchestra, which had amazed us in the first concert.

Riccardo Chailly’s Strauss odyssey with his Leipzig orchestra peaked in Saxony last year, the 150^th anniversary of the composer’s birth. I was lucky to catch a razor-sharp Till Eulenspiegel and a saturated Death and Transfiguration in Dresden’s Semperoper close to the birthday. 14 months on, and the Barbican has nothing like the same necessary air to offer around a mini-residency of richly-scored symphonic poems.

If you’re going to employ tens of extra musicians for Strauss’s gigantic Alpine Symphony, it’s probably just as well that a few other "biggies" are programmed in the same concert. So it was at the Philharmonic Hall, where the Strauss shared the programme with a new orchestration of Tchaikovsky’s The Seasons as well as a selection of Canteloube’s haunting Songs of the Auvergne. All three pieces are evocations of a place or a season, so this whole concert was almost a musical novel or an orchestrated visit to an art gallery.

“How fair is the Princess Salome tonight”! That slithering clarinet run, that glint of moonlight: few operas create their world so instantly and so intoxicatingly. At Symphony Hall, the lights rose on the very back row of the stage, the percussion riser serving as the terrace from which Andrew Staples’s Narraboth and Anna Burford’s Page exchanged their ecstasies and warnings. Beneath them, Kirill Karabits directed a surging, shimmering Bournemouth Symphony Orchestra with urgent, economical gestures.

“A rich and eclectic sequence of works” was the promise made in this evening’s concert programme. It certainly was that, with the Last Night festivities taking in new and old, well-known and obscure, plus a handful of celebrity soloists for good measure. The audience was predictably ebullient, generating the kind of atmosphere you only get at the Last Night of the Proms.

In 1989 Neeme Järvi, already rated one of the world’s top conductors and soon to be voted “Estonian of the Century” by his compatriots, returned with his Gothenburg Symphony Orchestra to the homeland he had left for America nearly a decade earlier. I went with them then, and to experience a free Estonia 26 years later was a bracing surprise.

In a curious deal, two operatic card games were running almost simultaneously last night. At the London Coliseum, Tchaikovsky’s outsider Hermann was gambling for his life on three hands of Faro in The Queen of Spades, while in home counties countryside, Robert Storch aka Richard Strauss thought he was relaxing from a performance with a nice game of Skat when in comes a telegram from his tricky spouse Christine, aka Pauline Strauss, unsigned as usual, accusing him of adultery.

“Songs of Vienna” by the Britten Sinfonia turned out to be a concert of chamber works, with never more than six performers on the stage at any time. It was built around two appearances by the Canadian soprano Barbara Hannigan, who performed pieces with voice by Chausson and Schoenberg. They are clearly part of her core repertoire, and she sings them with passion and from memory.
