This is more apparent than real, however, for the fleet pulse of the first movement is not a barnstorming, noisy parade, but is more akin to the swift thought of intense concentrated activity. It is salutary to compare this movement (indeed, one could with profit do so by using the entire Sonata) with Shostakovich’s more ‘public’ compositions of the same period, notably the Eighth Symphony (completed a few months after this Sonata) in which a similar profound impression is conveyed through broadly identical processes. Indeed, the structural device of placing the emphasis on the finale was carried a stage further in the Second Piano Trio opus 67.
The second movement, a lamenting Largo, forms the perfect foil to the fleet music of the first movement, but it is much more than that. As mentioned earlier, and like the Second Piano Trio, the B minor Sonata is a memorial work. It is dedicated to the memory of the Russian piano pedagogue and composer Leonid Nikolayev, who had died in October 1942 at the age of 64 in Tashkent (to where he had been evacuated following the Nazi invasion in 1941). He had been one of Shostakovich’s early teachers at the Petrograd Conservatory (he had been a professor there since 1906); in the Largo movement of this Sonata it is certainly not too fanciful to feel that this deeply affecting creation is a searching lament for this noble musician.
The relative clarity of the Sonata’s tonal structure acts as an anchor throughout the work: reasonably firmly rooted in B minor, it is the home key which pervades both the first movement and the finale; the Largo falls to A flat major/minor—the same interval, the minor third, from the tonic B minor which marked the opening of the Sonata’s first theme. The tonality now rises for the extended finale. The first themes of each of the Sonata’s three movements stretches the intervals—the first began with a minor third, the second with a falling fourth, the finale with a rising fifth—and this remarkable concluding movement could possibly stand as a separate piece, as an extended set of variations upon a lengthy, winding and curiously memorable theme (as it is fashioned from scraps of ideas). The moods in the finale are wide-ranging yet are impacted and continuously flowing. It is only with the concluding pages that the entire strands of the Sonata are at last brought together in a masterly act of synthesis: the swift semiquavers of the first movement are combined with the solemnity of the Largo through the main theme of the finale. It is a very remarkable compositional achievement, one’s only regret being that Shostakovich did not explore the piano Sonata medium as thoroughly as he did that of the symphony and string quartet.
