Musical theatre needn’t be dominated by the human voice. Instrumental dramas with an element of acting can be a good way into the wonderful world of chamber music for younger audiences, and the Wigmore Hall’s new gambit of special student tickets for contemporary music paid off with the very different crowd there last night. It was rewarded with playing of the highest imaginative order from soloists in their own right: violinists Patricia Kopatchinskaja and Pekka Kuusisto, viola-player Lilli Maijala and cellist Pieter Wispelway.

Pianist Mitsuko Uchida's concentration, calm and grace under pressure are an inspiration. Towards the end of the first piece on her programme, played to a packed Royal Festival Hall last night, the quiet but insistent high-pitched screech of a fire alarm kept going off. Low voices on walkie-talkies at the entrances to the hall were also audible. Whatever the confusion they were sharing with each other, they were failing to lift it.

What Anne-Sophie Mutter is to the violin, Alison Balsom to the trumpet and Sabine Meyer to the clarinet, so is Sioned Williams to the harp. Though Meyer had the glass-ceiling distinction of being the first woman in the Berlin Philharmonic, Williams’s service to the BBC Symphony Orchestra has been longer (nearly 25 years so far as principal harp). And while all four artists have had major new works composed for them, the harpist’s commission of six pieces to celebrate her 60th birthday would seem to be a record.

Staying close to his Scandinavian roots, John Storgårds, principal guest conductor of the BBC Phil and chief conductor of the Helsinki Phil, is gearing up for the celebration of Carl Nielsen’s 150th birthday next year. Being the seventh child of 12, Nielsen battled his way from poor beginnings to musical eminence, serving his time on the way as a military bandsman and, for 16 years, as a violinist in the Royal Danish Orchestra. He, too, always stayed close to his roots, even writing Danish popular songs to the end.

“Mahler, with a chamber orchestra?” In his introduction to the Scottish Chamber Orchestra’s winter season brochure, principal conductor Robin Ticciati anticipates the reaction of an audience brought up to believe that a chamber orchestra leaves its comfort zone somewhere in the early 19th Century.

Sir Mark Elder has a penchant for taking on large-scale works in Manchester, from operatic concert performances of Wagner and Verdi to Hollywood musicals. Following that line, he kicked off the new Hallé season with Ravel’s Daphnis et Chloé ballet score in its entirety, described by the composer as “a vast musical fresco faithful to the Greece of my dreams”. We are used to hearing the odd suite, but rarely the whole work. 

London homelessness charity The Passage was set up in 1980 and has been growing steadily so that it now provides a day centre, short-term hostel and long-term housing in an effort to help street sleepers get their lives back on track. Its annual "A Night Under the Stars" gala concert is the central event on its fundraising calendar, and assembles an extremely high standard of musician. The evening was compered by Jo Brand and Petroc Trelawny, both safe pairs of hands in their distinct ways.

Stratford-upon-Avon calling. The City of London Sinfonia has embarked on a series of three Bard-based October concerts in London to commemorate the 450th anniversary year of Shakespeare's death. The first of the three stopping-off points last night was Southwark Cathedral, in some ways a logical starting-place, since the building proudly asserts its credentials as the parish church nearest to the Globe Theatre.
