It does not seem like 12 years since the organ in the Usher Hall was restored to full working order. That may be because, in the minds of many Edinburghers, the recent years of untroubled service are still eclipsed by the many decades in which Norman and Beard’s monumental instrument sat silent, reproaching the City Fathers for their parsimony. Another reason, of course, is that in common with most concert hall organs, it is only infrequently called upon by the standard orchestral repertoire to provide that magical extra ingredient in the ensemble.

Howard Blake fans, look away now. Am Himmel wandere Ich isn’t a back translation of the hit song from The Snowman. Though the Marxist-Adornist supporters of the party line at Darmstadt’s summer course of 1971 could hardly have thought less of Stockhausen’s song cycle when they heard it and then circulated a dismissive pamphlet. ‘Saint Stockhausen’, they called him.

Great Estonian Neeme Järvi’s two conducting sons have had varying success in London this week. Kristjan did what he could with a dog’s dinner of a Britten Sinfonia programme on Wednesday night, while older brother Paavo presumably chose the three surefire masterpieces in his Philharmonia concert yesterday evening. The climax was Nielsen’s Fifth Symphony, one of the greatest of the 20th century; certainly there’s none to cap its sheer physicality.

Don’t blame the players: they did their considerable best. But what could they hope to achieve with a programme in which six of the seven pieces were on a hiding to nowhere, or too short to have much of an impact? A sequence, what's more, in which platform rearrangements took longer than two of the pieces in the first half?

“The first section, following a short introduction, places a rhythmic sequence on its retrograde. The two layers are transposed independently (one going up, the other down) as the music progresses, and points of symmetry are highlighted when they occur”. No, me neither. Apparently Patrick Brennan’s Polly Roe also features a brief rhythmic quotation from Birtwistle’s Carmen Arcadiae Mechanicae Perpetuum. More erudite ears may have been able to detect it.

Four years ago, Vasily Petrenko and the Royal Liverpool Philharmonic embarked on a two-year project to play all the Mahler symphonic works over a couple of seasons. It was an ambitious project but it was one which, then, had hall staff dusting down the House Full signs and the queues for returns forming well before the first note was due to played.

Christian Gerhaher is a classy recitalist. His stage manner is debonair, his tailoring immaculate (although his hair can be unruly). His artistry focuses on key vocal virtues: directness of expression and beauty of tone. In this evening’s recital, an adventurous programme that switched between the Classical era and the Modern, that proved as valuable a combination in Schoenberg as it did in Beethoven.

It was rather like a trip home to see long-lost relatives. Ton Koopman took to the stage at the Liverpool Philharmonic with a broad smile. That smile both greeted the audience and, from what the audience could see, told the orchestra that they were on form. Or, on the other hand, it might have been encouraging them to try harder.

A full house for a premiere performance: Wynton Marsalis bucks the trend in contemporary music. He’s an established name, more for his jazz than his classical work. But in recent years he has produced a substantial body of orchestral music, so the flocking crowds know what to expect. His new Violin Concerto continues the trend. Popular American idioms – mainly jazz and blues – are integrated into a classically oriented orchestral style with an impressive craftsmanship that hides all the joins.
