The stage of the City Recital Hall was unusually full for the Australian Chamber Orchestra’s concert on Tuesday night, their first Sydney stop on a tour featuring works by Mozart and Brahms. The core contingent of 15 or so string players was augmented to about 50 musicians by means of additional strings and a full roster of woodwinds, brass and percussion. Many of these players have prestigious orchestral posts overseas, and had presumably returned for the Australian World Orchestra concert a few weeks previously. The increased numbers enabled the orchestra could make one of its relatively rare incursions into 19th-century repertoire for Brahms’ Third Symphony. Even with their expanded forces, the ACO fielded far fewer players than a typical performance of the work by the Sydney Symphony Orchestra might, but such was the commitment and energy from the performers that no one could have felt they were being sonically short-changed.
At the beginning of the first half, director Richard Tognetti announced that the Orchestra was to perform the Overture to The Magic Flute as a sort of curtain-raiser to the Sinfonia Concertante, with no real break between them. The ACO delivered a vividly coloured account of the Overture: the off-beat accents were dramatically pointed, the woodwind solos sat beautifully on top of the string backdrop, and the few portentous brass passages were rich and round. While the ACO can (and usually does) perform Mozart with far fewer players, the fullness of sound was welcome, and came at no loss of their usual immaculate precision. This wasn’t mannered or restrained Mozart – rather, it was a rumbustious account of this familiar masterpiece, and the better for it.
The fan-like arrangement of strings for the first half was unusually symmetrical: first and second violins on the edges flanking divided viola forces, with the cellos sitting slightly further back in the middle. Sharing centre stage for the second work were the two soloists – Tognetti and violist Christopher Moore, with the latter walking into position during the closing bars of the Overture. Although not a ‘period’ group, the ACO has adopted the restrained use of vibrato from the historically informed performance (HIP) tradition, and also the practice of having the soloists join in during the tutti sections.
The Sinfonia Concertante, which Mozart might have called a ‘concerto grosso’ had he been writing a generation or so earlier, is structured so as to showcase both soloists separately (often the viola repeats a phrase just stated by the violin) and together (there are plenty of passages in parallel thirds and sixths). In the first movement, my impression was that Tognetti was holding back a little so as not to dominate the viola; by reason of its higher register and more penetrative sound quality the violin tend to cut through the texture much more readily.
