Criticism of Brahms' orchestration, so often concerned with supposedly clumsy couplings and other textural decisions, would have little to go on after a performance like this. The orchestral sound was lean, but never malnourished, exposing the frame without making it skeletal. Haitink's approach to the symphony did much to lighten the sonorities too, insisting on highly articulated phrases, so that the lines never lagged or became ambiguous in their direction. Furthermore, the relatively reduced string forces (actually akin to what Brahms would have expected) afforded a fleet-footedness that a larger orchestra simply could not offer, allowing the players to navigate Brahms' counterpoint with clarity rather than languor.
The instrumental playing was exceptional as well: woodwind sounds that ravished and string colours only imaginable in the intimacy of a quartet. Of course, such transparency also carries greater risks, and the antiphonal seating of the violin sections did not help secure every corner of the ensemble; yet, by way of counterbalance, the centred celli and basses provided a clearer gravity to the sound, particularly in the concerto.
And if Haitink had created an ideal orchestral mould, Emanuel Ax was its perfect complement. His sound was rich and warm: a gentle muscularity that could further shape and penetrate the COE's svelte figure. Just as the symphony had revealed its more chamber-like sonorities, Ax found the symphonic currents – and their subtler counterparts – in the concerto; indeed, this work had begun life as Brahms' first attempt at writing a symphony, in the wake of Robert Schumann's attempted suicide in 1854, which deeply affected the younger composer.
